LAS VEGAS (KLAS) — The FBI is offering a $30,000 reward for information leading to the arrest and conviction of a man accused of killing his girlfriend one year ago.

Tabatha Tozzi, 26, was shot on April 22 and later died. Oswaldo Perez-Sanchez, 27, committed a carjacking immediately after the alleged murder and has not been seen since, according to the FBI.

“He’s possibly in Las Vegas. We’ve had intelligence that he might be in California, even down in Mexico,” Ray Johnson, assistant special agent in charge at the FBI’s Las Vegas division said.

Las Vegas Metro police investigated the alleged murder. A task force including the FBI and the U.S. Marshals are searching for Perez-Sanchez.

“This case is, without a doubt, one of the most horrific incidents that have occurred to a family,” Gary Schofield, U.S. Marshal for the District of Nevada, said.

Schofield said he believes Perez-Sanchez’s loved ones may have information on his whereabouts.

“Most individuals that are on the run keep contact with their family,” Schofield said.

Regina Gomes, Tozzi’s mother, said she will continue to spread the word about Perez-Sanchez.

“He has to pay, you know, for what he did,” Gomes told NewsNation affiliate KLAS. “How can he just leave and they haven’t caught him?”

Gomes recalled meeting Perez-Sanchez for the first time after her daughter told her he had gotten a tattoo of her face.

“My heart tells me that’s not a good thing,” Gomes said.

On April 21, 2023, Gomes said Tozzi revealed that she would break up with Perez-Sanchez after trying for two months.

“I say, ‘Are you afraid that what he’s going to do to himself or to you?'” Gomes said. “And she say, ‘Mom, he’ll never do anything to me. Never, Mom.'”

Tozzi left the Summerlin home they shared.

“I said, ‘OK, please be careful,'” Gomes said.

Hours passed and Gomes received a call from her daughter.

“She was screaming. She says, ‘Mom, please come and get me’ and my heart dropped and I say, ‘Where are you?'” Gomes recalled.

Gomes said her daughter remained on the phone with her, as she told her Perez-Sanchez refused to let her take her car and leave.

This would be her last conversation with her daughter. Perez-Sanchez shot Tozzi in the head, stole her friend’s car and left the scene, according to police.

“He killed her in cold blood,” Gomes said. “He took everything from me.”

Gomes said she raised her daughter as a single mom and they were especially close.

Tozzi worked in Las Vegas nightlife and had a large social media following and many friends.

“She’s always been the light of my life,” Gomes said.

According to the National Coalition Against Domestic Violence, leaving an abuser is the most dangerous time for a victim of domestic violence. For more information, including resources visit this website.
