Pennsylvania handyman accused of sexually abusing multiple children, authorities looking for more victims

Police in Chester County, Pennsylvania, arrested a man they say sexually abused multiple children in West Whiteland Township, and investigators are looking for more victims, officials said.

During a news conference Monday, officials from District Attorney Chris de Barrena-Sarobe's office shared multiple photos of David Vincent Rosa, who has changed his appearance over time. Rosa is charged with child rape and more than 100 counts of possessing child abuse material. 

The investigation began in April in West Whiteland Township, where Rosa lived, after authorities got a tip that someone was uploading child pornography to a Google account. 

Prosecutors say Rosa recorded himself sexually abusing a girl between 2 and 6 years old. After his arrest, investigators said, they found additional victims, including one woman who was abused in a van while she was unconscious. 

Rosa, who was a residential painter and handyman, was transient and had previous addresses in Philadelphia, Allentown and Malvern, officials said. 

"It is one of the most terrifying sexual assault cases that we have come across in some time," de Barrena-Sarobe said. "I cannot begin to describe how invested this entire team is in getting justice for victims and proving our cases beyond a reasonable doubt in a court of law."

Officials said he gained access to his young victims because he sometimes stayed at customers' homes during jobs. 

Detectives are concerned there could be more victims who have not yet come forward. 

Officials said Rosa had more than 1,000 pictures and videos of child pornography on his phone and Google accounts. The investigation extends into Northampton and Monroe counties.

"The creation of something like a non-consensual intimate image, whether it be a still picture or a video recording, is tremendously damaging," said Jennifer Simmons Kaleba, who works with RAINN, the largest anti-sexual violence organization in the U.S. 

The district attorney encouraged anyone who has had contact with Rosa to speak to the authorities.

"If you or someone you know has spent time with David Rosa, please contact the Chester County detectives at 610-344-6866," de Barrena-Sarobe said.
