>> yes. >> instead it says what? >> it says it's mandated that he have supervised visits with him, that he has a parental right to see him. >> what did you think when you read that? >> shocked. it didn't make sense to me they took his right as a parent even over the safety of the child. >> what's more, under arizona law, dwight was entitled to spousal support. in this case $6,000 a month. >> he threatened you, hit you, says he is going to murder you, murder your child. >> mm-hmm. >> you have to pay him spousal support. >> yes. >> and you're on the hook for his attorneys. >> yes. yes. and i have to pay for the supervised visitations because he is a threat. >> what did this cost you financially?

>> it was not. >> meaning that if it's dwight jones, he still has that gun with him? >> right. and meaning they don't necessarily have enough yet to link dwight jones to these four murders. >> but there was still the dna. a detective who flew late sunday night to get dna samples from dwight's family now rushed those swabs back to the lab and -- >> within about four hours, we had a positive hit on mr. jones. >> we at "dateline" cover a lot of murders, some of which take years to solve. this case was not one of those. less than 84 hours after this homicidal rampage began, investigators were confident they had id'd their killer. >> we knew who was our suspect and murderer. >> at the same time the dna was being analyzed, detectives were retracing dwight's steps. they believed that sometime before he'd been placed under surveillance, dwight had contacted the residents of this home in fountain hills. they sent a maricopa county sheriff's deputy to check on them. >> they used a ladder. they got to see through an upstairs window, and they immediately recognized that there was a gentleman inside that appeared to have been shot. they forced entry, and upon doing so, found another victim, a woman, who had also been shot, and both were deceased. >> my guts just absolutely dropped when i heard this news. >> scott wightman was the tennis coach of one of the victims, mary simmons. >> she competed like nobody else. everybody wanted to play with mary. >> and one of her occasional playing partners was dwight jones. police believe, that for reasons yet unknown, dwight murdered mary and her boyfriend, bryon thomas, in their home. remember that .22 police observed dwight tossing?

>> yes. >> with a tremendous amount of courage and with rick's help, connie jones and her son had lived to see her personal terrorist's last i do this earth. >> but other people were killed, innocent people, good people, productive people, that is a hard thing to come to grips with. >> six people gone, three of whom apparently had nothing at all to do with dwight jones. just in the wrong place, at the wrong time. like the paralegals, laura anderson and veleria sharp, both in their late 40s, both wives and mothers. neither had worked on the jones case. >> i've heard people say -- they mean well -- that god needed another angel. i think that's a bunch of mularkey. if god needed another angel, i'm sure he could get one. he didn't need to come and take veleria and take a mother and take a wife to get one. >> and the therapist, marshall levine. >> if you'd been in your office and not marshall levine, i kind of doubt you'd be sitting here talking to me today. >> i'm sure that's true. >> what's that like? >> that's hard to think about. i don't really know how to think about that, to be honest. >> the grief is still raw for natalie collins. >> you going to change the way you live? >> i hope not. i don't think steve would want that. he was not about hiding in the shadows. i am not going to let him have died for nothing, and i will find a way to make him proud. >> no one can say for sure exactly what set off dwight jones. after the bloodshed was over, some videos surfaced that jones had posted before the murders. >> hello, youtube, welcome to my channel. >> in them dwight raged against his wife and the professionals who worked on the custody case. >> you've ruled i have a psychiatric problem based on some piece of -- that she hired? >> the videos underscored some troubling questions. dwight jones was obviously disturbed, so why wasn't he stopped? did the legal system fail everyone? could six murders have been prevented? >> i do feel very strongly that the court system did not protect me. >> connie jones says her ex-husband was violent for years, but that courts ignored one red flag after another. >> my life wasn't valued. my son's life wasn't valued enough to stop him, which inadvertently harmed other people. >> if she had to live all those years terrorized, we failed her as a society. and i think as a physician with the resources she had, i wonder how many other women and families that we're failing as a society. >> most people can't take the steps to cover their tracks the way connie did. >> does the court system, both criminal and family court, do those systems understand domestic violence? do they react to it in the right way? >> no, not necessarily. >> allie bones is the former ceo of the arizona coalition to end sexual and domestic violence. >> they've had no problem whatsoever taking a position, a strong position, around duis or driving under the influence. but for some reason, we have had a very hard time over the years making the same argument with regards to domestic violence. >> habitual drunk drivers are quickly and legally separated from their car keys. but dwight jones, a documented domestic abuser, did not lose his right to own a gun. after holding his son captive in that standoff with police in 2009, he was allowed to plead guilty to disorderly conduct, which did not prevent him from legally buying the handgun he used to kill. and there was the mental health treatment strongly recommended by dr. steven pitt and ordered by the court. dwight didn't go. >> but the court did not follow up with that. there was no consequence for that. >> just before his death, steve pitt was proposing a story to "dateline," about educating people to see the warning signs of oncoming violence. >> there are always red flags and warning signs. it's not about blame. it's about prevention. and if we don't teach people what those signs are and we don't modify our system so people know who to reach out to, then we are failing. >> my message to any domestic violence victim out there is you're responsible for your own safety. >> if you count on the system to protect you, you make a mistake. >> you are making a mistake. i went in very naive. >> the sad truth is that some stories don't have happy endings. sometimes, particularly in real life, the bad guys win. but maybe connie and rick are the best living proof that some beauty can blossom from even the darkest of situations. >> a friend of mine told me that he really likes you. and i said, no, he doesn't. he is my friend. when i started paying attention to it, and i was like, oh, i think he does. >> what did you like about her? >> it turned out at my age, what was important to me is not only that she's beautiful, but she's intelligent. >> somehow, out of fear, danger, and the need for protection, grew love. connie and rick married in december 2013. you did your job. you protected her. she's still here. >> i'm happy about that. >> you feel like, maybe, the universe owes you a little happiness here? because i do. [ laughter ] >> well, we are. we have a very good family. i'm proud of it. i've been married twice. this is the only husband i've ever had. that's all for this edition of "dateline." he was coming towards me. his arms rais. i started pushing back. he grabbed me. i was shaking. i said, stop. stop. what are you doing? stop? >> they had a charmed life by the beach, surfer dad. >> he was a stud, you
