A Carrollton murder suspect has killed himself in a standoff involving Van Alstyne police.
Jomaar Lee Davis was suspected of murdering his girlfriend, Briana Casto, on October 20, according to a release from the Carrollton Police Department. Then he reportedly killed himself on October 21 in a Van Alstyne police standoff.
Carrollton police responded to a medical emergency near 4600 N. Josey Lane around 10:12 a.m. on October 20, according to the release. When they arrived, they found 24-year-old Casto dead from an apparent gunshot wound.
After investigating, detectives identified Davis as the main suspect. While they searched for him, officials obtained an arrest warrant for murder. On October 21, the Celina Police Department shared information suggesting Davis was near Van Alstyne.
The Collin County Sheriff’s Office notified the Van Alstyne Police Department around 3:30 a.m. about Davis’ possible location, according to a release from the department.
“The suspect’s phone was actively pinging in the Van Alstyne area,” the release reads.
Van Alstyne police responded and quickly found Davis, barricaded in Casto’s vehicle.
Other agencies also responded, including the Anna Police Department, Howe Police Department, Carrollton Police Department, Grayson County Sheriff’s Office, and Collin County Sheriff’s Office.
“Crisis negotiators established phone contact with the suspect; however, communication was later cut off by the suspect,” the release reads. “Members of a SWAT team subsequently approached the vehicle, at which point a gunshot was heard.”
The Grayson County SWAT team tried approaching Davis in an armored vehicle, but he shot himself. Responders brought him to a local hospital for treatment, where he ultimately died.
No officers or civilians were injured in the shooting, which is currently under investigation. Carrollton police asked members of the public to call 972-466-3333 with additional information.
Van Alstyne police thanked first responders for their help.
“Officers did a great job containing the situation ensuring the safety of the public,” the release reads. Nearby Partin Elementary School delayed the school day due to the standoff.
A suspect in a triple murder in Mabank crashed into a Buc-ee’s before shooting himself on October 17, as The Dallas Express also reported. The day before, a Mansfield man was booked into the Tarrant County Corrections Center on a $1 million bond for attempted murder.
