Syracuse police arrested a Layton man Wednesday for allegedly sexually abusing two girls, and officers believe there may be more victims.

Police booked Robert Lloyd Zesiger, 30, into the Davis County jail on suspicion of one count of aggravated sexual assault, and three counts of forcible sexual abuse. He was also being held for violating his probation with federal authorities for possessing child pornography.

Syracuse police Lt. Tracy Jensen said a 14-year-old girl from Syracuse told her parents about being sexually abused by Zesiger. During an interview with police, the girl brought up the name of another 14-year-old neighbor girl who might have also been involved with Zesiger.

Jensen said one of the incidents possibly involved a weapon being used against the victim.

The two neighbors knew Zesiger through his girlfriend.

"Basically he befriended them over time and sexually abused the two girls," Jensen said, adding that based on Zesiger's past history "these may not be the only victims."

Zesiger, a registered sex offender in Utah since his 2007 federal conviction for possessing child pornography, has a history of sex crimes involving children.

Zesiger pleaded guilty in 2004 to a lesser charge of class B misdemeanor of attempted lewdness involving a child, according to court records. In 2007, he was convicted of a 2005 offense of attempted sexual abuse of a child, a third-degree felony.

Syracuse police urge anyone who may have been victimized by Zesiger to come forward and contact them at 801-825-4400.
