Arrest made in torture, murder of 21-year-old woman after weeklong manhunt for her boyfriend

A person is in custody following a dayslong manhunt after a Bronx brute allegedly tortured and murdered his 21-year-old girlfriend and dumped her body in a stairwell.

Princesa Encarnacion-Soto was stabbed from head to toe, possibly beaten with a hammer on July 22 and left to die on a staircase at the Fordham Heights building on Grand Concourse near East 183rd Street, cops said.

On Thursday, the NYPD released a photo of Robert Strother, Encarnacion-Soto’s boyfriend and the suspect in the slaying, after searching for him for more than a week.

Encarnacion-Soto was staying in the building Strother and his mother, 54-year-old Naida Jorge, cops said.

Police could not confirm Strother was the person arrested but were preparing charges, they said Saturday.
