The man charged with murder on Audelia Road last week was wearing an ankle monitor while out on parole, The Dallas Morning News reports. He is now being held at the county jail.

Police say the victim, 39-year-old Brian Dillard, went to the apartment of the girlfriend of 36-year-old Zeric Jackson Nov. 3 to sleep with her. While she showered, Jackson allegedly shot and killed Dillard. The girlfriend heard a loud bang and found Dillard on the floor.

Dallas Fire and Rescue pronounced Dillard dead about 4 a.m. at the apartment on Audelia near Walnut Hill.

Jackson’s parole officer told police his ankle monitor tracked him to the woman’s apartment complex from 3:25 a.m. to 4:05 a.m., the same time she heard the bang and called 911. It then showed Jackson driving to his home in southern Dallas, The News reports.

The woman told police Jackson had a gun and told her two days before the shooting he planned to kill her. Police found extensive damage and blood spatter in her home, which she said was from a previous assault by Jackson.

Jackson pleaded guilty to deadly aggravated robbery in 2005. He was part of a group involved in a robbery outside the Neon Cowboy bar, where two people were fatally shot. He was sentenced to 18 years in prison and was out on parole at the time of the Audelia Road murder.

Jackson is being held on $1 million bond.
