As part of their ongoing investigation into the gruesome killing ofOrsolya Gaal, detectives are looking to speak with a handyman who they believe is familiar with the layout of the Queens, N.Y., home where police believe the mother’s killing took place, according to law enforcement sources.
The New York Police Department sources tell PEOPLE the handyman has not been declared a suspect or person of interest.
However, investigators believe that Gaal and the handyman at one time had a romantic relationship, and that it is likely he was aware of where the family stored a spare key to their Forest Hills residence, the sources confirm.
The sources could not discuss the alleged relationship in any detail.
Gaal, the mother of two teen boys, was stabbed more than 50 times, and sustained blunt force trauma to the head.

Officers followed a blood trail from the duffel bag back to the house some nine blocks away.
Police have recovered surveillance footage showing the suspected killer wheeling the duffel bag away from Gaal’s home sometime between 4 and 4:30 a.m., the sources confirm.
Additionally, the sources say that Gaal had been communicating with at least three men in the days prior to her murder.
Sources tell PEOPLE there were defensive wounds to Gaal’s hands, indicating she tried fighting off her attacker.
Gaal, who was a stay-at-home mom, lived at the house with her husband and two sons, ages 17 and 13.
