SACRAMENTO, Calif. (AP) — Acting amid extra tight security, parole commissioners on Friday again recommended the release of a former leader of the Mexican Mafia prison gang who now helps law enforcement, Board of Parole Hearings spokesman Luis Patino said.

Rene "Boxer" Enriquez has been in prison since 1993 on a 20 years-to life sentence for two murders, multiple assaults and conspiracy to traffic in controlled substances.

It's the second time parole officials decided that he can safely be released. However, Gov. Jerry Brown last year rejected parole for the 53-year-old Enriquez and Brown has about five months in which he can block it again.

"Hopefully this time the governor will let him go home," Enriquez's attorney, Michael Beckman, said after the hearing.

Brown last year rejected Enriquez's parole in part because of concerns that he would be targeted for retaliation by other gang members if he is released. That could endanger Enriquez, his family, parole agents and the community, Brown said.

That concern was reflected in Friday's hearing. Prison officials kept the timing and location of the hearing secret, citing safety concerns for Enriquez and prison employees.

Los Angeles County Deputy District Attorney Steve Sowders said three survivors were allowed to use only their first names as they testified against his parole by video conference.

"They're concerned about their safety," he said. "This is because of the case involves the Mexican Mafia."

Enriquez drew attention last year when the Los Angeles Police Department used an invalid court order, spent $22,000 and cleared a downtown Los Angeles building so Enriquez could speak to a gathering of law enforcement and business leaders.

He has talked in recent years to various groups of officers and provided valuable information on the transnational criminal enterprise to which he once belonged, Los Angeles Police Deputy Chief Michael Downing said afterward.

Enriquez cited his cooperation and the self-improvement classes he has taken in prison as he spoke for more than three hours Friday, according to a Los Angeles Times reporter who watched by video conference. The reporter described him as sitting like a businessman at a board meeting before the two-person parole panel, his hair slicked back and cut short on the sides.

Enriquez described how his mother died shortly after the speech controversy and Brown's denial of his parole, calling it one of the most difficult periods of his life — "blow after blow after blow."

"We believe you have insight into your behaviors ... and how you can avoid those behaviors in the future," parole Commissioner John Peck told Enriquez, according to the newspaper.

Sowders said there were more than 60 letters from law enforcement agencies supporting Enriquez's parole. He acknowledged that Enriquez has provided valuable assistance.

However, he argued Enriquez has failed to fully accept or explain how he rose to become a leader of the infamous prison gang. That was among the reasons Brown gave in denying parole last year.

Enriquez wrote a book about his gangland experiences, "The Black Hand," using a nickname for the gang also known by its Spanish language initial, La Eme.
