A suspect is in custody after an aspiring Hollywood actor was stabbed to death in what the LAPD says was a “confrontation turned deadly.”

Marvin Monterrosa, 28, was arrested on Jan. 31 on suspicion of murder for the New Year’s Day attack on Robert Mosca, 50, police told CBS Los Angeles.

Mosca and two friends were reportedly approached by his assailant as they were walking from a New Year’s celebration to Mosca’s apartment early on Jan. 1, according to the creators of a GoFundMe page dedicated to pursuing Mosca’s killer. One of Mosca’s friends yelled “Run” before the suspect attacked Mosca.

“Rob fought with him, and when he got away, Rob ran to his friends and said, ‘I think I’ve been stabbed,’” according to the GoFundMe page. “Rob then ran up his driveway and collapsed.”

North Hollywood Area patrol officers responded to a call of an assault at the corner of Sarah Street and Vineland Place at around 1:35 a.m., according to the LAPD.

Paramedics with the Los Angeles Fire Department responded to the scene and transported Mosca to a local hospital, where he died from his injuries, according to the LAPD.

Police initially had no information on a possible suspect, according to the Jan. 4 release.

It was unclear what information led to Monterrosa's arrest weeks later, or what motive, if any, he would have had to attack Mosca.

On Friday, the organizer of the GoFundMe page announced the “cold-blooded” alleged murderer’s arrest.

“Hopefully, by the time this guy goes to trial and is convicted, he will go to jail for life,” the campaign stated. “And never see the outside until he’s buried in the ground.”

Robert Mosca was a Philadelphia native who’d moved to Hollywood to pursue his dreams as an actor, according to ABC 7. His acting credits included work on “The People vs. OJ Simpson” and as an extra on “Dr. Ken.”

“He was not one of these people that sat around waiting for the phone call,” Mosca’s friend, Brian DiLoreto, told ABC 7. “Like, he was out there every day, every other day, trying to make things happen.”

“All who have met or worked with Rob knew him as a beautiful person,” his GoFundPage stated. “He was a good friend. If you ever need[ed] him, he was there for you."

Marvin Monterrosa is being held at the Valley Jail in Van Nuys on more than $2 million bail, jail records show. He is expected to appear at the Van Nuys Courthouse on Feb. 16 at 8:30 a.m.
