Prosecutors say dozens of women may have been sexually abused by a Bay Shore man and not even realize it.

Raul Guaman, 43, was arraigned in Riverhead Tuesday morning on an 11-count indictment. Guaman is accused of posing as a ride-share driver, then sexually abusing and recording the acts on women who were passed out.

Prosecutors say he is a sexual predator who was in possession of 16 driver licenses and 32 cellphones that he kept as trophies. Police say they are investigating if the victims were drugged and have no recollection of their encounter.

“In my almost 37-year career, this is one of the most shocking cases I've ever seen,” said acting Suffolk Police Commissioner Stuart Cameron.

Guaman is also accused of video recording a Brightwaters woman through her window on Nov. 14 and then breaking into the home to sexually assault her sister. Cameron says he fled when the woman woke up.

In court on Tuesday, police said Guaman was under police surveillance after that burglary. Four days later, Guaman was observed not stopping for a stop sign on East Third Avenue and Spur Drive North in Bay Shore, court documents say. He was then placed under arrest.

The father of one of the victims sat in court for the arraignment. At the end, he angrily yelled at Guaman: "Raul, look at me!” He then cursed at him.

Guaman is in the U.S. illegally from Ecuador and was held without being allowed to post bail. His defense attorney entered a not guilty plea for him but declined to comment on the case.
