Jesse Alexis Chavez heard the screams from the hotel bar, police and prosecutors said. A co-worker had just been held up at gunpoint during a robbery, and Chavez ran to the lobby to her rescue.

But as the hotel manager struggled with the armed man attempting his getaway, prosecutors said, the tussle spilled out to the portico of the building. A gun fired, and a bullet tore through Chavez’s chest, leaving him dead.

“He made what would be the final decision of his life,” prosecutor Christine Murphy said. “Jesse chose to be a hero.”

Almost two years after the October 2013 shooting at the Clarion Hotel in Oxon Hill, a Prince George’s County jury Wednesday convicted Deandre Weems, 22, of first-degree murder along with armed robbery, assault and other related charges in Chavez’s slaying.

The evidence and witnesses presented over the course of the two-and-a-half day trial were fairly straightforward, according to prosecutors. Surveillance video showed a man jumping the counter in the hotel lobby and pointing a gun at the woman, who was five months pregnant.

Witnesses testified that they saw Chavez, 27, run to the woman’s aid and struggle with the gunman before getting shot in the chest. Police collected a gun connected to the shooting from Weems’s home.

“You know it’s the defendant because you can see it with your own eyes,” Murphy said as a screenshot from the surveillance video of the robbery was shown to the jury alongside a photo of Weems.

William Warner, who was in the hotel at the time of the robbery, said he was standing about 12 feet away from Chavez when he saw a gun fire at Chavez’s chest at point-blank range.

“He fell down in front of me after that happened,” Warner said.

David Booth, the attorney for Weems, attempted to cast doubt on the surveillance videos presented as evidence. He said the video’s timestamp shows the robbery occurred at 9:21 p.m., when cellphone records show his client was not at the hotel, but about five miles north of the area.

And there was no DNA evidence of fingerprints collected from weapons, Chavez’s body or the hotel linking Weems to the crime.

“Sort of like isn’t the same as it is,” Booth told the jury.

But prosecutors said the clocks on the video cameras ran 40 minutes behind.

Chavez’s family sat quietly in the audience throughout the trial. They held one another’s hands as the judge read jury instructions. And his mother, Vivian Chavez, rolled rosary beads through her fingers during closing arguments.

His family said while his death was shocking, they were not surprised to learn he was running to help a colleague. Nicknamed “Mr. Latinbear,” his mother remembered how Chavez came home with tales of having to remove rude people from the hotel restaurant to protect employees and customers.

“I don’t think he was thinking to try and be a hero,” Vivian Chavez said. “He knew that she was pregnant and anybody that has a daughter that’s being attacked would hope someone would come to her aid.”

Two other men, the alleged getaway driver and lookout on the night of the robbery, have also been charged in Chavez’s slaying. Kimfrey Williams, 26, and Rinaldo Washington, 20, are both scheduled for trial in October, the same month Weems is set to be sentenced.

Booth declined to comment after the jury reached its verdict.

Prince George’s County State’s Attorney Angela Alsobrooks said Weems “had no regard whatsoever for life.”

Chavez’s family said they miss the son who was not ashamed to hold his mother’s hand in public or the brother who would dress as Santa Claus every winter.

“The loss of my son was really, really big,” Vivian Chavez said. “I’m still hurting.”
