BOSTON (WHDH) — Police named a person of interest in the death of Amy Lord, whose body was found in the Stony Brook Reservation in Hyde Park Tuesday afternoon.

Edwin Alemany, 28, is currently the only person of interest in connection with Lord’s death. Boston Police Commissioner Edward Davis said they are waiting for DNA evidence to link Alemany to Lord’s death. He said it takes time, but did not say how much time.

Davis added that police do not have any evidence of a second suspect in Lord’s case.

“It’s incredibly frustrating that we’re here today talking about a man that has 18 juvenile arraignments, 34 adult arraignments and is still not incarcerated,” said

Sources told 7News Lord, 24, was assaulted in the hallway of her South Boston apartment building before being forced to withdraw money from five ATMs in the Boston area. She was then stabbed to death and her body was found in a wooded area of the Stony Brook Reservation. Her burned car was found Tuesday morning in South Boston.

Alemany is charged with stabbing one woman and punching another in separate incidents in the same South Boston neighborhood within a 24-hour period around Lord’s killing. A source told 7News Alemany was spotted at the hospital by one of the women he allegedly assaulted. That helped police link him to the crimes.

He was scheduled to be arraigned for the two attacks on Thursday, but it was canceled after a court psychiatrist determined he was suicidal. He is undergoing a 20-day evaluation at Bridgewater State Hospital.

Court paperwork obtained by 7News shows Alemany has an extensive criminal record that includes assault and battery. He was released from jail in July 2012.

Davis said police are reviewing every assault on a woman since Alemany has been out of jail.

Police are specifically looking into a case from Sept. 2012 where Alemany’s wallet, including his identification, was found at the crime scene of an assault victim. The victim could not properly identify her attacker and Alemany was never fully investigated for the crime.

Police said they are launching an internal investigation in the Sept. 2012 case.

People who live in South Boston said they hope the man in custody will answer a lot of unsolved questions and give everyone a peace of mind.

“We just hope that the gentleman that they have in custody right now, they are able to link him to her. It will bring a little relief to South Boston,” said Jackie Brown, who lives in that area.

A vigil was held Friday outside of Amy Lord’s apartment in South Boston. Police want to make sure that young women in the city feel safe.

“Walking around at night, I do go to my car late at night. It makes you more vigilant when you’re going to your car or going home,” said Jessica Mooney, who also lives in the area.
