A New Bedford man who robbed a person at knifepoint in Dartmouth in 2019 has been sentenced to up to four years in state prison, Bristol County District Attorney Thomas Quinn announced March 15.

Luis Santos, 22, pled guilty in Fall River Superior Court to indictments charging him with three counts of armed robbery. According to a press release, Santos and his girlfriend Kerstyn Gross, 23, would set up unsuspecting men through dating websites and rob them once they came to meet with Gross.

The first reported incident occurred on Jan. 31, 2019 in Dartmouth. 

According to the release, Gross picked the victim up at his residence after meeting him on the website “Meet me.”  While driving, she pretended to have a flat tire and stopped the vehicle, only for Santos to jump out of the woods with a knife and robbed the victim.

Santos then entered into Gross’ car and fled the scene, leaving the victim stranded with no cash or cell phone. 

None of the stolen items were ever recovered from this incident.  

The duo would conduct similar robberies in New Bedford later in 2019.

Along with Santos’ sentencing, Gross pled guilty in New Bedford District Court last September to charges of larceny from a person.  

She was sentenced to two and a half years in the Bristol County House of Corrections in Dartmouth, with one year to serve and the balance of the sentence suspended for three years.  

She was also ordered to undergo mental health counseling and to stay away from Santos and the victims.
