Arlington police have arrested a 27-year-old man believed to be responsible for the death of Kennedale Junior High School English teacher John Ross Shreves. Patrick Jardell Brooks was booked into Arlington City Jail on June 13 and is facing a murder charge.

Shreves, 27, was shot and killed in an Arlington sports bar parking lot around 2 am on June 10. Police found Shreves slumped over the drivers seat of his car outside No Frills Grill & Sports Bar in the 4900 block of Little Road. Police say the car window had been shattered.

Shreves' death was one of four Arlington murders in less than a week and the only one to date that has resulted in an arrest. Police say none of them appears to be related.

An elderly woman was found dead in her home in the 5300 block of Wild West Drive on June 9. Family members told police they had been unable to contact her. Signe Edwards, 67, had obvious trauma to her body, and her death is being investigated as a homicide.

A 19-year-old man was shot and killed in South Arlington around 11 pm on June 5. Unlike in the other deaths, police believe Donsha Hughes may have known the person who killed him. Hughes reportedly received a phone call shortly before stepping outside and being shot.

Another elderly woman was carjacked, abducted and killed on June 4. Leona Faye Swafford, 83, was pulling into her driveway around 8:30 am when a man attacked her. Swafford's body was later found with head trauma.

Unlike the murders of Hughes and Edwards, Swafford's case has a suspect. Her killer is described as a black man in his late 20s to 30s, around 6 feet tall with short hair and a muscular build. Oak Farms Dairy is offering a $10,000 reward for any information leading to an arrest and grand jury indictment of the person responsible for Swafford's death.

Anyone with information on any of these unsolved crimes is asked to call Tarrant County Crime Stoppers at 817-469-TIPS.
