A man found inside a white van linked to a Lunar New Year massacre that left 10 people dead and 10 others injured in Southern California was found dead Sunday afternoon from what authorities say was a self-inflicted gunshot wound. 

Law enforcement sources told Fox News that the man shot himself and died following a police standoff with a "barricaded suspect" in a van in Torrance, located roughly 30 miles southwest of Monterey Park, where Saturday's shooting unfolded.

No additional details were immediately available. 

"I want to address also that there is a tactical incident that's occurring in the city of Torrance," Los Angeles County Sheriff Robert Luna said during an earlier press briefing. "People have asked is that your suspect? We don't know."

"It's a barricaded suspect situation. We are working with one of our partner agencies, the Torrance Police Department, to resolve that. We believe there is a person inside of that vehicle."

Luna said that police were working to resolve the standoff in the "safest manner" and that the person inside the van could "possibly" be the mass shooting suspect.

Local reports later Sunday stated that a body was reportedly found inside the van.

"A body has been found inside the white van that allegedly belonged to the Monterey Park mass shooting suspect," Bryan Hernandez, a producer with News Channel 3-12, reported on Twitter.

Officials confirmed that 10 people were killed and at least 10 others were injured and taken to local hospitals after a man opened fire on people shortly after festivities for the Lunar New Year wrapped up in the city on Saturday. The shooting was carried out at Star Ballroom Dance Studio on West Garvey Avenue at about 10:22 p.m., according to authorities.

The victims include five men and five women and were all "probably" of Asian descent, according to Luna.

Monterey Park is located about 10 miles from downtown Los Angeles and has about a 65% Asian-American population, the L.A. Times reported. Authorities described the suspect earlier Sunday as an Asian male between the ages of 30 and 50, they but did not release additional information or a potential motive for the shooting.

The sheriff's office released the first photos of the suspect on Sunday, showing a man who stands at about 5 feet 10 inches tall and weighs 150 pounds. He was wearing a hat, glasses and a winter coat in the photos released by authorities. They said they were withholding the suspect's name.
