A San Francisco man who allegedly trespassed on multiple San Mateo school campuses last month and briefly abducted a 9-year-old girl pleaded not guilty to all charges against him in San Mateo County Superior Court Wednesday afternoon.
Bradley Mrozek, 25, is accused of walking onto three campuses on Sept. 21 including Parkside Elementary School, where he entered a girl's bathroom and grabbed a student, covered her mouth with his hand, and carried her off campus, District Attorney Steve Wagstaffe said.
New DNA evidence has prompted the district attorney's office to change one of the charges against Mrozek from committing a lewd act on a child to committing a sexual act with a child under the age of 10, Wagstaffe said.
The girl was able to fight off her abductor by kicking him and throwing rocks, and she ran back to the school campus and immediately reported the incident.
Police responded and identified Mrozek as a possible suspect in two other incidents that occurred at separate schools earlier the same day, Wagstaffe said.
At Bayside STEM Academy -- a middle school in San Mateo -- Mrozek allegedly trespassed on campus and made contact with as many as four students, making lewd comments to two girls and offering alcohol to two boys, according to prosecutors.
The suspect is also believed to have trespassed at Horrall Elementary School, where he was escorted off campus by an administrator.
After Mrozek was arrested on Sept. 22, investigators connected him to a fourth incident that took place in March at George Washington Elementary School in Daly City, Wagstaffe said.
A man went into a girl's bathroom on campus and tried to take pictures of girls using the facilities from a stall, prosecutors said. The girls heard clicking noises and immediately reported it to a teacher.
When the teacher entered the bathroom and ordered the person to come out, a male suspect ran out of the facility, Wagstaffe said. Prosecutors believe Mrozek was the intruder, he said.
Mrozek now faces a total of 18 separate charges, including child molestation, kidnapping, child annoyance, attempting to possess child pornography and offering alcohol to a minor, Wagstaffe said. He remains in custody without bail.
