USC linebacker Osa Masina being investigated by police in 2 states

— -- USC?linebacker Osa Masina is under criminal investigation in two states -- California and Utah -- for separate incidents, a spokesman for the Cottonwood Heights (Utah) Police Department confirmed Tuesday.

Police documents obtained Tuesday showed?authorities are looking into allegations of sexual assault in the Utah case, but no charges have been filed.

"We have an active investigation on Osa Masina," Cottonwood Heights Police Department Sgt. Dan Bartlett said. "We are working with [the Los Angeles Police Department], who also has an active investigation."

Bartlett would not confirm any specific details about the investigation, but he did say a search warrant was served to Masina on campus at USC last week. Documents show the alleged incident happened July 30, before Masina reported to USC training camp.

The Los Angeles Police Department on Tuesday said it has interviewed Masina in relation to a case it is investigating but would not provide any further information regarding his involvement or the nature of the case.

Bartlett said the alleged incident in Utah happened after an alleged incident in Los Angeles.

Masina's family has retained Salt Lake City-based attorney Greg Skordas, who confirmed there are two incidents being investigated and that Masina -- a Utah native who was a standout player at Brighton High School -- remains in Los Angeles.

"What was taken [during the search] I can't talk about, but apparently they are going to do their investigation based on that search warrant," Skordas said.

The only discipline Masina has faced, as of Tuesday afternoon, has come from the athletic department, Skordas said. He will not travel with the team for Saturday's game against? Alabama?in Arlington, Texas. He did, however, practice with the team on Tuesday.

A sophomore inside linebacker, Masina is listed at No. 2 on USC's depth chart. He made 25 tackles in 12 games last year.

"USC is aware of the investigation involving student-athlete Osa Masina," the school said in a statement. "USC is cooperating fully with authorities in Utah, the lead agency in the investigation. Due to privacy laws and to protect the rights of our students, we are not able to discuss this matter further."

USC coach Clay Helton repeatedly cited privacy laws when asked about the investigations after practice on Tuesday and said he will defer to the university when it comes to discipline.

"Really, as a coach, you're taken out of it," Helton said. "This is a university and a policy and I'm confident in the guidance of the university here, so they'll let me know."

Quarterback Max Browne acknowledged that news about the investigation could cause a distraction but said the team will try to stay focused.

"Yeah, it's tough, but at the end of the day, we've had a lot of distractions in the past," Browne said, "and we'll leave that to Coach Helton to address."
