It has been extremely hard. The hardest part was the picture of our mom. I always told myself she didnt see it coming. A mother at work in her office, murdered. Someone just shot her and let her die. Making sure she was dead. Who wanted this very nice, professional woman dead . Police starts to dig. Her new fiance. He was like i had to move on. It was just very suspicious. Her final client. He owned a Nine Millimeter gun. Her exhusband. He was under deep suspicion by the whole town. He was. Did you murder your wife . I know he was capable of doing anything. But we would know, we are his kids. A chilly case. Agreed, hate, murder. With a riveting and. Moms killer is still out there. Hello, and welcome to dateline. Pam zimmerman was everything to her three children. Cheerleader, confidant, mentor. A reassuring presence who was always there. Then, she was gone. Shot dead in her office. But why . In the search for clues, detectives focused on the men in pams life and the secrets they kept. Only one would face trial for her murder and the setting up here pams family apart. Here is Keith Morrison, with before mid night. A few minutes after sunrise on the morning of november 4th, 2014, David Zimmerman rose through his bed in the christ summer of a bloomington illinois, eager to dispose of the small worry that had been nagging at him all night. He patted across the room to his bedroom door. Woke up and walked out into the main hallway that we havent the lights are still on. The lights he left on, but he went to bed, which meant what . David was 17 years old, the eldest of Pam Zimmermans three children. They, not uncommonly, left their lights on for their mom when she left late for her Financial Planning business, or when she stepped out with her new man. Typically, when she got home she turned the lights off. But this Tuesday Morning . Her bedroom was dark and it looked like someone had been there. Tell me what was going on in your mind when you saw that . My mind was probably 1 million different places. I thought it was the weirdest thing. It was like, all right, she e, didnt come home, so where is she . Had to be a reasonable explanation. Pam zimmerman was so reliable. R two years divorced, a successful businesswoman and fully engaged mother. A pillar of the neighborhood. David and his 15yearold twin sisters, heidi and rachel try to push their worries aside. We made up every possible excuse for why she wasnt coming home. You dont want to focus on t that. But some signs were hard to ignore. For one thing, the night fo before, when pam didnt respond to her kids text messages, heidi tried tracing it. What she found didnt make sense. My mom and i had an Iphone Account, so i looked it up, i found it wasnt at her office. It was in a weird location. I convinced myself that she was at a clients house, because at that was my excuse at the time for why she wasnt home still, their mom was a rock. They told themselves they would be laughing about this later. Or they would be relieved anyway. They said, lets just get ready for school, keep mom with her day. So you kept going . Yeah. Same time, say morning, two doors down the street, one of pams closest friends, judy cool, was still in her pajamas. My home phone rang, which was odd, because your home phone never rings that early. It hardly ever rings ever. Im one of the few people that still has a home phone. And so, i picked it up and it was scott. Scott baldwin was zimmermans beyonce, he lived a few hours away in chicago. He said i havent heard from pam i am worried. I dont know what is going on. I have been trying to reach her since last night, she is not answering. She left just a couple of houses down here right . Right. She is a few houses down there. So i walked down here, and ke knocked on the front door. And david answered. R. And i said where is your mom . He said i dont know, she didnt come home last night. And i said, what you mean she didnt come home last night . I said, well, where is she . I believe they have been trying to reach her, since 5 30, the night before. And she didnt answer. For the kids, she tried to hide the Worry Flooding into her brain. Shes like okay, just go to school like you normally would o and i will text you later when i know something. Maybe, thought julie, there was some simple explanation. She rushed home, got dressed, sh jumped in her car and headed straight to pams office. Maybe pam fell asleep while working late . I dont really know, i dont know what my thinking was. Pams kids try to concentrate on their school work. Couldnt. I just remember going to school and rachel and i sat across from two of our friends at school and i just lost it, started bawling in the whole morning was hard. By now there was a tribe of people. This is pams cousin, vicki. I have a brother who is 18 years younger than me. He called and he said they cant find pam, and i go what . W he goes, they cant find pam. I said that is not good. He goes, no it is not. The drive to pams office didnt take long. Julie cole pulled into the he parking lot. Right away she saw something that would lead her to call 911. Coming up, an awful discovery at pams office. The lights were all off. All of the sudden i hear her say, oh my god, oh my god, oh my god. I remember thinking everything has changed in my life right now. Everything has changed and those kids, there is david and his cheeks are stained with tears. When dateline continues. Started disrupting my day. Td felt embarrassing. I felt like disconnecting. I asked my doctor about treating my td, and learned about ingrezza. Ingrezza ingrezza is clinically proven for reducing td.

Foul yah . Foul bro here take a free shot go ahead knock yourself out. Your about to get served. Seriously . Get allstate, save money, and be better protected from mayhem, like me. Love you mom wait till your father gets home. And theyre all coming . Those who are still with us, yes. Grandpa whats this . Your wings. Light em up gentlemen, its a beautiful. Day to fly. Its a beautiful. Day to fly. Wooooo we are talking about him and not only talking judges, but family members. To the margins that matter. Dont miss the weekend on 8 00. On msnbc. 7 00 a. M. , november 4th, 2014. Julie cho, full of trepidation, right outside of the Business Office of her missing friend and neighbor, Pam Zimmerman. Nobody around, except wasnt that pams car in the lot . Julie called her husband. He said call 911. So, i called 911 and she said, you want to file the missing persons report . And i said i dont even know if she is missing. But then she saw someone who could help. Right as i pulled in, she was getting out of her car and walking towards me. Right. So i jumped out of my car and i said pam didnt come home last night. Pams friend and Longtime Office manager. She said pam seemed fine the day before. Said, when she left around 4 30 p. M. Pam was with her last client of the day behind closed doors. The two women headed in. The lights were all off the lines were all pulled. Was that unusual . Barry, the blinds in my area were never closed. They were this time . They were closed. And i reached over and turned the light switch on. And i hear her say oh my god, oh my god, oh my god. And i walked over to where she was and we could see pams body, kind of laying in a fetal position. Julie is a nurse, she checked for signs of life. I remember leaning down and, you know, checking for a pulse, and thinking everything has changed in my life right now. Everything has changed for those kids, and their life will never be the same. So, there are two things . Right. Right, you are trained, you immediately focus, your emotions are aside, i knew something was bad, i knew something wasnt right, i knew not to move her. Has stared, rooted to the spot. I went into shock, i saw her lying there. But you have no idea . No. She could have had a heart attack . Could have. Or maybe she tripped behind the Reception Desk . In the back of my mind im like, did she had her head . Police arrived within minutes. Julies phone, still pinging. I keep texting, think someone needs to go and tell them what is going on. Eventually, officers went to the high school. One by one, pams children are called to a conference room, where the police told them their mother was dead. That was the worst part, they brought me to this room and theres david, and his cheeks are stained with tears. I just had to see that, and they told me and i was just falling is david starts falling again. Half an hour later, the same thing happens with rachel. Oh lord. I cant imagine a day like that. You know where your dad was . Did you know where any sort of savior of your life was . No. No anything like that. They just took us into question. But that it was hard for anyone to focus on anything other than loss, allconsuming grief. She was the greatest friend, anything you could ask for, you needed something she would have it in a hard. She would talk to anybody, everybody knew her. She made everybody feel like they were you know, one of her closest friends. She was sincere. A caregiver, that was Pam Zimmerman, but to her sister, diane gifford, and brother, larry alexander, pam was also the familys smart ambitious start. Valedictorian of the class. Graduating class. Straight a student, retired, grade school and high school, except, i think 1b. When she got home act. I mean, ive always known, we have had the most amazing mom. Such a bright happy person, full of wisdom, smart, funny, i could go on and on. She always made sure that we came first. She would come home from work. She would make us dinner, she would stay up all night helping us with homework or doing our laundry. Recalled her super mom, because she literally did everything. And for all of the love she inspired, Pam Zimmerman must have stirred something dark in someone. Or got in someones way. It wasnt long before the police figured out that her death was no accident. What did the police tell you . Nothing. They kept the evidence very, very quiet. What did you find out how she was killed . A few Days Later Police called me and said that the newspapers wanted to release information and i should tell the kids and the only thing they would tell me is the cause of death was multiple gunshots. Pam zimmerman had been murdered. But by whom . Coming up, police start with the men around her, her new fiance. We had at least two other women that he had been involved with. Or final client. He owned a Nine Millimeter. She was shot with one of those. And what about her ex . When dateline continues. Before Apoquel Chewable for allergic itch, giving dogs pills was a battle of wits.

Pamela zimmerman was the victim of coldblooded murder. Happened sometime before midnight, there was no doubt, Pamela Zimmerman was the victim of old blooded murder. It happened sometime before midnight, as the corners best guess. The Murder Weapon . The Nine Millimeter handgun. There were two Bullet Wounds in her chest, in the front of her body. Edith brady is a long time panty grab a crime reporter. There was one bullet room in her temple, and there was one bullet wound in her back. So, somebody making absolutely sure she was good and dead . Absolutely. What was that like to hear that . It was the worst phone call of my life. To think that someone shot her and just let her die. And pams kids . When they heard that i always told myself she didnt see it coming, it made it easier to cope with it. An execution was what it looked like it or maybe an opposite invasion robbery. It didnt seem likely but they wanted to do a walk through to see what was missing or what was out of place. Did you notice anything wrong . Anything missing . The phone cords had been cut. And my calendar that i kept all of my appointments on, that was wrong. Pams purse was sitting on her desk, gaping open. Her wallet was gone, cell phone too. The case was lying on the floor. Did you get the sense that maybe the police thought somebody wanted to steal something and were in the process of it and got interrupted or . They could have thought that. But there was no sign of forced entry, none. The cops found pams cell phone right where her daughters Iphone Account said it would be. Her wallet, close by, with her credit cards all there. So, the police believed early on that this was a staged effort to make it look like it was a robbery. But who would want to kill pam and then stage them halfhearted coverup . Start close is the old adage, which meant coming pams world on that day, three men, her last client and last day of her life, her exhusband, and her brandnew fiance, Scott Baldwin , the object of a whirlwind romance, and perhaps rapid engagement. After all, no one in the family really knew him, not even her kids. I had only met Scott Three Times and the third time was the party that they had to celebrate their engagement. That celebration was just days before, yet when scott heard about the murder, he did not rush to bloomington from his home just two or three hours away, near chicago. It just made me realize i think what my mom really meant to him, what we meant to him, it sounded fake at that point. Pams kids had questions about scott and soda detectives. He was asked to come down to wilmington to meet with police, which he did the following day, after pams body was discovered. Scott told the detectives he had been home alone, when pam was killed. Police would look into that, but in the meantime they discovered something very interesting. About pams new fiance. They spent a fair amount of time checking into who he had been communicating with. Sure. He had at least two other women that he had been involved with that he was still having some pretty heavy amount of contact with. Pams kids didnt know anything about that, but they did get a weird vibe from the fiance after their mothers death. He was like, i have nothing to do with this and i need you guys to understand that i have to move on. Repeat that for me . We had dinner with him, like a week after she died, and he sat us down. Did you ask him if he had something to do with it . No, he just volunteered that. Two months later, he was dating someone new. It was just very suspicious. But pams daughter, rachel, thought it was much more likely her minds murder was tied to her business. She was an accountant and financial advisor. Maybe she found out something that one of her clients have been doing on this client would have lost a lot of honey. Ina hess said her last client was a man, named eldon with low. To they hav
