Escaped Serial Rapist Found Hiding Under A Mattress

Yesterday, police warned that a dangerous convicted rapist on parole in San Fernando had cut off his GPS monitoring device and disappeared. Police found him last night, hiding underneath a mattress. Joseph Serapiglia, 43, was arrested this morning around 2:45 a.m., City News Service reports. Police found him hiding in a home in the 36000 block of Auburn Court in Palmdale when they responded to a burglar alarm. Prior to his arrest, he had last been seen on Friday in Panorama City.

When deputies arrived, they first found Adrian Madrigal, 40, who couldn't seem to come up with a reason for why he was at the house. Police detained him and began searching the home. Eventually, they found Serapiglia hiding beneath a mattress.

Sgt. David Sauer said that Serapiglia first tried to give the deputies a number of fake names, but that they eventually figured out he was the escaped parolee. Serapiglia was arrested and will be transferred to county jail after he appears in court for outstanding warrants.

Madrigal was arrested for being under the influence of a controlled substance.

Sauer said police aren't sure yet if Madrigal and Serapiglia knew each other, or if Madrigal had anything to do with helping him hide.

Serapiglia had been serving a 42-year-sentence for the rape and attempted murder of a 31-year-old woman in 1991, but was released on parole after only serving 23 of those years. Serapiglia tricked the woman into accompanying him on a drive by telling her his father had gone missing. Once he got her to a remote location, he raped and beat her, then stabbed her six times and threw her down a hillside. Though Serapiglia left her for dead, the woman was able to climb back up the hillside and find a group of people who drove her to the hospital. Serapiglia also has 'oral copulation with a minor under the age of 14 by force or fear' on his listing on the Megan's Law website.

We have reached out to San Fernando officials to find out why he was paroled, but have not yet heard back.
