Arrest made in Delaware and Raritan Canal State Park sexual assault

A Raritan Borough man has been arrested for the sexual assault of a woman who was walking on a path along the D&R Canal State Park near the border of Plainsboro and South Brunswick last September, Middlesex County Prosecutor Yolanda Ciccone said.

Rogelio Calyeca Postrero, 38, has been charged with first-degree kidnapping, two counts of first-degree aggravated sexual assault, second-degree sexual assault, first-degree robbery, and weapons charges. Postrero is being held in the Somerset County Jail pending a detention hearing, law enforcement officials announced Wednesday afternoon.

On Sept. 28 of 2021 between 4:30 p.m. and 5 p.m., a woman was walking along the path adjacent to the park when she was approached by a man armed with a knife. The man dragged her into a wooded area, demanded money, and sexually assaulted her.

Postrero was charged earlier this month with sexual assault for attacking one woman on a trail near Blackwells Mills and Canal roads in Franklin Township, and attacking another woman at Duke Island Park in Bridgewater. Police were able to solve all three crimes after Postrero was arrested and charged with lewdness for masturbating near a park on Aug. 4. Police realized that his description matched the suspect’s descriptions in the assault cases. They executed a search warrant at his home and found a bicycle that matched the description of the bike in the Franklin Township assault. According to the prosecutor’s office, a forensic analysis confirmed that Postrero’s DNA matched the sample obtained from the Bridgewater assault.

The Middlesex investigation is ongoing. Anyone with information is asked to contact Detective Christopher Pennisi of the Middlesex County Prosecutor’s Office at (732) 745-3600, Detective Patrick Miller of the Plainsboro Police Department, or Detective Dominick DeLucia of the South Brunswick Police Department at (732) 329-4646.
