DALLAS – A Dallas Police investigation into a double homicide continues after the suspected gunman was found dead from a self-inflicted gunshot wound in Mesquite, authorities announced.

Double murder-suicide investigation

What we know:

Dallas officers responded to a shooting call in the 15800 block of El Estado Drive in Far North Dallas at 2:40 p.m. on December 11, 2025. The preliminary investigation determined that two people had been shot.

The victims were identified as 24-year-old Arlina Sander, who died at the scene, and 27-year-old Darvilease Washington, who was taken to a local hospital where he later died.

The Miami Hurricanes have won five of their last six games early in the 2025-26 regular season. Head coach Jai Lucas has done a great job recruiting and finding the right talent for the Hurricanes; however, that is when they get a chance to see the court.

Entering this season, the Hurricanes struggled to stay healthy. Four-star freshman Treyvon Maddox hasn’t even seen the floor yet, while the rest of the team is trying to find a good footing.

Against UL Monroe, star five-star freshman Shelton Henderson went down with a lower leg injury with 1:29 left in the first half. It seems he avoided a major injury, warming up in the second half, but Lucas decided not to put him back in the game.

“We’re still kind of evaluating and seeing what it is,” Lucas said after the victory over the Warhawks. “He tried to kind of go out there and start the second half, run around a little bit, so we’ll see.’

However this is the tip of the iceberg with the injuries for the Canes.

UM is playing playoff levels with this tight rotation. Starter are playing 30-plus minutes against quad-four teams because of the lack of bodies.

Marcus Allen and Donte Allen have missed every game since the Hurricanes defeated Ole Miss on the road. Ernest Udeh Jr. has been in and out of the line all season. Noam Dovrat has a nagging shoulder injury that will keep him out of the game; Tru Washington has missed time; Tre Donaldson is powering through some little nicks; and now the Henderson injury.

The Hurricanes have the talent to be a Sweet 16 team in the NCAA Tournament, but they have to be on the floor at all times. The Hurricanes are only playing seven players a game right now, and it will either help them or hurt them.

The Hurricanes are set to face the FIU Panthers, while they try to get healthy at the right time. The Hurricanes are dominating on both sides of the ball, but the challenges from opponents will continue to increase.

“I expect a war,” Lucas said. “They’re really good. [FIU head coach Jeremy] Ballard’s done a good job this year with his team construction,” Lucas said. “They play with confidence. They play free. They’re aggressive. They’re big. They got really good guards.”

Prediction

76ers 114, Hawks 111

BET 76ERS (+155).

The Hawks have fallen off a cliff, and their defense has gone with them. They are 1-4 over their last 5 outings and have allowed at least 123 points in 5 of their last 8 games. Their offense hasn’t matched that shortcoming, scoring 100 points or fewer in 2 of their last 5 contests.
