When No One Would Listen (1992)

I too seen the movie and really liked it. I always try and look up any information on a true movie as in trying to find the real names the location, the trial etc....Here is what I have found so far. I hope this helps.

David was found guilty of first-degree murder, attempted first-degree murder and first-degree assault in the 1987 shootings. He faces at least 40 years in prison before parole, and prosecutors have said they will seek the death penalty. David Guenther -- 6-foot-5, 260-pounds -- beat Pamela regularly for 15 years. Her close friends knew it. But she stayed with her husband, who was unemployed and apparently universally disliked. When she finally left David, Pamela took her two children and secretly moved in with her boss -- who later became her lover. David -- who in 1986 killed a neighbor woman and wounded her husband in a bloody quarrel on the doorstep of the Guenther home in a Denver suburb -- tried to kidnap Pamela in a doughnut shop parking lot and threatened her life repeatedly.

After she got a restraining order forcing him to leave their home so she could move back in, he forced his way into the house and held her hostage at gunpoint for four hours before surrendering to local police.

Yet, eight hours after David was arrested, he was out on $10,000 bail, charged only with burglarizing his own home -- a fact that outraged Pamela's friends and neighbors. He began stalking Pamela, who hid from him in a shelter for battered women and insisted upon -- and got -- police escorts to her supermarket job. A week after the hostage episode, David jumped out of his car in a parking lot and shot Pamela to death in front of their children. He is serving a life sentence for first-degree murder.
