>> after looking at the scene, it became obvious that the scene was staged. >> staged? >> yes. >> it was meant to look like a robbery. however, nothing was taken of note. there was money left, keys left. >> stuff that would've been easy to grab and get a little money? >> yes sir. >> nothing was disturbed other than the bodies found. >> and the csi team found something else. the way the intruder may have entered the home. the point of entry you found to be? where they wanted you to believe it was where? >> the garage door had a pain glass inside of it. and the glass was broken. and it was made to look like someone had entered the residence through that door. >> it may have looked like the intruders way in, but the curtain on the glass panes was undisturbed. it looked as though no one had pushed inside to grab the door handle. there was a much simpler explanation for how the killer, or killers had gotten in and out. they found the families outside key. it was kept hidden, and was missing from its usual place. >> and there was a key inside the doorway. >> the key that was in the doorway was probably the one that was kept outside? >>one would assume, yes. >> so you're looking at somebody who has at least good working knowledge of that house. >> yes sir. >> strange clues, at a grim scene. in those early morning hours. nothing seemed to be adding up. you have no idea who the shooter is?

any secrets in the esteemed heidt family? >> at this time we start what we call victimology. and victimology is something where we look at these peoples live, and determine what put them at added risk to -- >> he had to learn more about the patriarch, philip's business in -- the age and started by looking at the core of things, the immediate family. they would be a prime source of information, but something else as well. >> part of the investigation is that everyone is a suspect at this point. >> the detective began his interviews that morning after the family murders, sitting -- chris height. chris told the detective that he had been home with his wife the previous. night she was questioned, and the middle son's story checked out. by then, the crime scene analysts believe the murder weapon was a 12 gauge shotgun, and agent barry search chris home looking for a fire arm. >> he had several guns there. but nothing in my training, or experience, that indicated that any of them had been recently fired. >> next up, the detective. the older brother. craig heidt. >> craig stated that he was watching television shows. hunting and fishing shows. >> he told the gbi man that he had spent the night at himself at a place a half an hour drivers away. a rustic hunting cabin owned by a friend. agent berry drove up to the cabin to search it as well. >> the search of the cabin resulted in not finding any 12 gauge shotguns. >> but investigators did find 12 gauge ammo in the back of craig's truck. three inch magnum shotgun shells. >> he didn't tell me anything because craig heidt was identified as an avid hunter. and was known to turkey hunt. >> two days after the murders, the agent sat down again, with craig heidt at the sheriff's office. >> how is your mama doing? >> she is doing wonderful. >> she is? >> wonderful. >> after the polite formalities, barry posed the difficult question. who would want craig's family dead? >> craig offered this clue. >> the only thing that my father and carey has remotely said anything to me about anything is finances. >> craig may have been referring to the fact that his father philip, and brother carey, like so many others. had recently been spreading the plunging value in the 2008 real estate market. investigators would learn that the father son team of philip and carey ran a business worth millions. but they were heavily invested. land rich? maybe cash poor. had something gone dangerously downhill in philip heidt's empire? there were some complicated partnerships to examine. >> once this happened, there were numerous rumors about who did it. and if the market can do it or was it a professional hit? or did someone local do it. >> and he was a player. he had a lot of interest. how to state money? >> he did. >> and it's not unreasonable for investigators to get a deal to go south there? >> exactly. was this a bad deal that somebody got mad about and came to retaliate for. >> and craig heidt had perhaps another clue to offer detectives. he had been after the family property after the shootings and said that he noticed some of his things missing in the shut out back. including, a 12 gauge firearm. >> the 12 gauge is not there. i have one pair of snakebite boots that are not there. >> could the assailant had stolen those items to commit the crime? but, there was something else gbi agents was starting to get wind of. right rumors around town of a possible skeleton in the heidt family closet. investigators knew it could be nothing or something. but they would have to run down the scuttlebutt before they could move on to other leads. if only one family member would be more candid with them. after all, the rumors were about him. >> have you been totally honest with me throughout this entire investigation? >> yes sir. >> about everything? >> yes sir. >> coming up. >> maybe if i had went in april, to miss london, mr. philip, and carey. this is what's going on. you should do something now. maybe it would not have went to the limit. >> someone who had been keeping a secret. and it was about to come out. when dateline continue. ocks out your worst allergy symptoms including nasal congestion. without knocking you out. feel the clarity and make today the most wonderful time of the year. claritin-d. this isn't charmin! no wonder i don't feel as clean. hurry up dad! i'm trying! this cheap stuff is too thin! here's charmin ultra strong! ahhh! my bottom's been saved! woohoo! with its diamond weave texture, charmin ultra strong cleans better with fewer sheets and less effort. what's everybody waiting for?

this story that she hadn't told? >> i wish to the stay that i had. maybe they still would be here. >> tina didn't know anything about phillip's financial pressures. or a missing gun from the property. but she did know something about bottled up secrets. some people would later call it, scandalous, what had happened behind the heidt's closed doors. she had began her story with only good things to say about the parents. people she'd known for several years. >> miss linda and mr. philip heidt were very nice people. very carrying people. >> she met the son craig at the veterinarian's office where she worked laid back in 2003. they chatted about the hunting dogs, and she was struck by well mannered he was. >> very nice guy. very polite. just did the yes ma'am, no ma'am, thank you for helping me. that kind of person. >> craig and tina began going out. and when craig went on disability, after hurting his back at work, he had plenty of free time to drive the hour from effingham county, to the town where tina lived. he was there when she needed him, she recalls. came to leave on him for support. because at 42 years of age, tina was battling breast cancer. >> if i had a treatment, and i was very sick, he would be there with me. hold my hair if i was sick. he really was very supportive at that time. >> after nine months of dating, craig and tina started making wedding plans. >> we talked about who was going to stand up with us. and who we wanted to invite. and, just had really set a date. and, we really were serious about having a life together. >> but a month before the wedding day she found out something disturbing. really disturbing. tina was on her way to a chemotherapy treatment when she got a phone call. on the other end of the line, a woman's voice. >> she said, you are seeing my husband. >> and i said no ma'am i'm not, i'm not dating anyone's husband. and she said, yes you are. and i said tell me what your husband is? and she said craig heidt and i said, well wait a minute. i guess maybe i am. >> whoops! a controlled craig soon showed up on her doorstep. professing his love for her and saying that he foolishly hoped that he would get a divorce before she found out he had a wife and two kids back in effingham county. >> and i told him, you need to go home. take care of your business. get your divorce, stay with your wife. do whatever you're going to do. >> craig left tina's house, and within a few months he did get divorced. soon, he and tina were back on course. and he asked her to move up to effingham county. >> you won't have to work and i can take care of you. and, i know your health is bad. and we can have this life. and things will be better. >> but in fact, things were about to get a whole lot worse. and not just for tina and craig. back in effingham, craig's younger brother carey, was having his own relationship problems. carey told his friend james that his wife robbyn wanted a separation. >> it hurt him. he was torn up. he had made the comment to me about, you don't know how it feels live besides someone in the bed that doesn't love you. >> rob had found that carrie was sent too much time at work. so good husband that he, was he cut back his hours and went to counseling. anything he could do to make it work. >> he would do what it took to keep the marriage together. especially for the kids. i mean, he wouldn't want to see his kids grow up like that. >> but just as much as the kids, he didn't want to lose the wife who was his first and only love. the light of his life. >> they still told me that day that he loved robyn. he loved her dearly. last that i work, he still tried to make his marriage work. >> and while they were trying to keep their banged up marriage together, carey's older brother, craig, and his girlfriend tina, we're going through pretty much the same thing. tina had moved in with craig, but then he stopped coming home. and then one day, his stuff was just gone. >> i called him and i said have you moved out?
