here's another real life case that kind of sounds familiar -
Killer Grandma on Snapped!
Grandma Ann Trexler moved to Florida to spend more time with her granddaughter. When the girls father decided to move her to Montana, Ann hired a hitman to bring the relocation plan to a dead stop.
When grandmother Ann Trexler relocated to Florida, it wasnt just to spend her retirement years in the sun. Ann wanted to spend more time with her oldest daughter, Tina, and her six-year-old granddaughter. Tina shared custody of the child with her ex-husband Ron, an arrangement that worked well until Moms Ann moved to town. Ann threw herself into her role as grandmother, and resented the childs closeness with Ron and, especially, Rons new wife. In August of 1998, Ron petitioned the court to give him primary custody, telling the court that his ex-wife and her mother were disrupting his daughters school and social life, cursing his new wife in front of the child, and their hostility was affecting the girls physical and mental health. But the court never had a chance to rule on Rons petition. On the morning of October 6, when Ron opened the door to leave for work, a shot rang out. As Ron ran back into the house the shooter followed, shooting him eight times, while his panicked wife called 911 from the bedroom. Before he fled, Rons wife heard the shooter say, This is for her. Ron bled to death on the kitchen floor, curled up in the fetal position. Investigators believed Ron had been targeted for execution, but when the alibis of the usual suspects his current wife and his ex checked out, the investigation stalled. The break in the case came when police found the murder weapon, and traced it back to local hairdresser, Kim Miller Ann Trexlers hairdresser. Faced with a murder charge, Kim confessed that Ann had frequently wished aloud that Ron was out of the picture, so Kim hooked her up with someone who could make that wish come true. Using Kim as a go-between, Ann paid a man $10,000 to take Ron out. At her trial, prosecutors used Kims confession, bank records showing the money trail, and cell phone records to prove Ann was behind Rons murder. The defense claimed Ann was an innocent, church-going grandmother who was being framed by a drug addict working the system to get out of a murder charge. But the jury didnt buy the innocent grandmother act they took just two hours to find Ann guilty and sentence her to life in prison.
