After more than six years in custody, a Clay County woman has plead guilty in the murder of her nephew at a residence west of Dean.
At about 3 p.m. Sunday, June 17, 2007, Mary Ann Colvin shot and killed 49-year-old Davy Lynn Colvin of Petrolia at her home in the 300 block of Sue Lane, near the Clay-Wichita county line. After a witness called 911, deputies from Clay and Wichita County arrived to find Davy Colvin’s body in the driveway of the residence, and Mary Colvin sitting on the front porch of her home.
In the plea agreement, reached in the 97th District Court on Monday, March 11, Mary Colvin, 73, was sentenced to six years, nine months in prison. She has been credited with six years, eight months and 26 days. She remains in the Clay County jail.
Davy Colvin had been helping care for his aunt. According to Times Record News archives, the shooting occurred as Davy Colvin arrived to check on her.
One witness told The Pioneer Sentinel that he heard a gun shot as he and his wife were pulling out of their driveway. They looked to see Mary Colvin fire at Davy Colvin two more times.
According to an arrest warrant affidavit, a witness stated he heard a gunshot and looked out to see Mary Colvin with a revolver in her hand, firing shots. The affidavit states that after the first shot, Davy Colvin “hopped” toward, and fell behind a pickup parked in the driveway. Mary Colvin walked around the vehicle and fired twice.
A .38-caliber handgun believed to have been used in the murder, as well as at least one other firearm were removed from the home.
On June 15, 2007, two days before the death of Davy Colvin, Clay County Judge Kenneth Liggett contacted Adult Protective Services in an effort to get Mary Colvin a mental health evaluation, but to no avail. According to Times Record News archives, it was the second call from Liggett to APS in a week. The first call, June 10, 2007, resulted in a physical evaluation, but not a mental evaluation, said Liggett. Mary Colvin had undergone a psychiatric evaluation in February 2007.
Mary Colvin was arrested and charged with murder June 18, 2007, with bond set at $25,000. She was moved to Vernon State Hospital in December 2007, and returned to Clay County in 2008 and twice in 2009 for competency hearings.
Colvin has been in the Clay County jail since Aug. 3, 2009.
