Los Angeles police were warning local residents Tuesday about a "violent" registered sex offender who escaped to an unknown location after cutting off his court-ordered GPS monitor.
Joseph Serapiglia, 43, was last seen Friday in Panorama City near the intersection of Sepulveda and Roscoe boulevards. At some point, he cut off his monitoring device, according to a news release from the Los Angeles Police Department.
His whereabouts were unknown as of Tuesday morning.
Serapiglia was considered a "dangerous felon who has exhibited a violent nature" and a threat to Southern California communities, according to LAPD's Registration Enforcement and Compliance Team.
The convicted felon was sentenced to 42 years in July 1991 for attempted murder and rape, the release stated.
"We have a parolee at large who is of great concern to us," LAPD Lt. Paul Weber said. "He is a threat to the public."
He was convicted of attempted murder, rape and kidnapping, Weber said.
According to the Megan's Law website, Serapiglia's offenses included rape, oral copulation with a minor under the age of 14 and sexual penetration of a victim with a foreign object.
He served 23 years in prison before being released to live in San Fernando on April 16, 2014. His last known address was given on the Megan's Law website as 3557 Fletcher Ave. in Glassell Park, which is the location of a Presbyterian church.
Serapiglia was described as Hispanic, with brown hair, brown eyes and a bushy mustache. He stands 5 feet 11 inches tall and weighs about 175 pounds.
He has a dragon tattoo on his right upper arm, a marijuana leaf on his chest.
Anyone with information about Serapiglia's whereabouts is urged to contact Detective McPartland at 951-809-1647 or Officer Sanchez at 818-669-5511. During non-business hours and on weekends, callers should dial 1-877-527-3247.
