What we know:

Carrollton police initially responded to a shooting call in the 4600 block of North Josey Lane on Monday at approximately 10:15 a.m. Officers found 24-year-old Briana Casto, who had died of a gunshot wound.

Investigators identified her boyfriend, Jomaar Lee Davis, as the primary suspect and obtained a warrant for his arrest. Police used the warrant to track his cell phone location, which was pinging in Van Alstyne.

Van Alstyne Police Locate Murder Suspect

Van Alstyne police were notified early Tuesday morning, around 3:30 a.m., that the suspect was possibly in their jurisdiction, less than 24 hours after the shooting. Officers responded to the area where the phone was pinging and quickly located Davis’ vehicle. He was barricaded inside the car.

Negotiators made contact with Davis by phone, but he ended the call. As a SWAT team approached the vehicle, officers heard a single gunshot. Davis had shot himself, police said.

First responders administered lifesaving aid at the scene before transporting him to a local hospital, where he later succumbed to his injuries.

What they're saying:

Jan Langbien, CEO and founder of Genesis Women's Shelter, said the case is a reminder of how deadly domestic violence can be.

"She is not dead because she let him back in or he came back," said Langbien. "She's dead because he shot her. Until we get really serious about holding accountable perpetrators of these domestic homicides, they are going to continue to happen. 

Langbien says the message is particularly strong this month, which serves as a period of awareness for domestic violence. 

"I hope you don't just say, ‘Wow, that is a shame.’ I hope we all stand up as a community and say enough is enough of this," Langbien said. "There is help. There is hope. And it's never her fault."

Local perspective:

No officers were injured during the incident. Multiple agencies from Collin and Grayson counties assisted the Carrollton Police Department in the operation, including the Collin County Sheriff’s Office, the Grayson County Sheriff’s Office, and the Anna and Howe Police Departments.

Due to the proximity of the police activity, Partin Elementary School delayed its opening on Tuesday.
