SALINAS, Calif. — A Monterey County Juvenile Hall officer is accused of sexually molesting a 15-year-old girl while she was an inmate, Salinas police said Tuesday.

The victim told Juvenile Hall staff in Salinas that a 44-year-old juvenile institutions officer, Jesus Alvarez, " inappropriately touched her over a period of several days," Salinas police said.

The victim came forward in March, and the Salinas Police Department took over the investigation.

"A Salinas Police detective conducted several interviews with staff, other residents and watched hours of video while investigating this case," police said.

Alvarez is a former longtime Greenfield Police Department officer, and he began working at Juvenile Hall in February of 2017.

He was arrested Monday and booked into the Monterey County Jail on suspicion of child molestation.

According to inmate records, Alvarez had been freed from custody by Tuesday afternoon.

The Monterey County Juvenile Hall officer was arrested just five days after a Santa Cruz County jail guard was arrested and accused of abusing his authority to have sex with a female inmate in jail. Fired corrections officer Marco Del Real declined to enter a plea in court Monday.

Monterey County Chief of Probation Marcia Parsons said investigators do not suspect Alvarez had more than one victim.

"Salinas police interviewed several other female residents in our Juvenile Hall," she said.

Police Sgt. Christopher Lane said, "No one else has come forward."

During the month that passed between when the girl accused Alvarez and when he was arrested, Alvarez was re-assigned to the boys unit of Juvenile Hall, Parsons said.

He was placed on paid administrative leave immediately before he was arrested at the Monterey County Probation Department.

So far, Salinas police have reviewed 40 hours of surveillance videos from Juvenile Hall, Lane said.

During his time fighting crime in Greenfield, Alvarez received multiple outstanding officer awards, including officer of the year.
