Authorities in Pennsylvania say a 43-year-old woman murdered two elderly women at a home in Montgomery County last week.

According to the New York Post, Naseema Sami is accused pf bringing her 6-year-old son along with her when she approached the home on West Indian Lane in West Norriton Township.

Montgomery County District Attorney Kevin Steele said the suspect had previously lived at the same property about two decades ago, at which time 78-year-old Lila Frost was her landlord.

Local police reported to the location on Sunday evening to conduct a wellness check on the resident. Upon arrival, they reportedly found the bodies of Frost and Gigliello — in addition to Sami and her son hiding underneath a bed.

Investigators believe the suspect and boy entered the apartment through an unlocked door on Thursday. No one was home at the time, and Sami allegedly answered a knock at the door to find Gigliello, who had been attempting to visit Frost.

When the victim reached for a phone to call police, Sami allegedly killed her. At some point after that, Frost reportedly returned to the residence and police believe Sami also killed her and attempted to cover the tracks by cleaning up the area with bottles of bleach. Nevertheless, police reported finding a “very bloody scene” inside the apartment.

Medical examinations revealed both women died as the result of homicide. The cause of Gigliello’s death was listed as head trauma and Frost is believed to have died from a number of injuries.

“Our hearts go out to the families of these two victims and pledge to them that we will seek justice for their murders,” Steele said.

An affidavit submitted in the case indicated that Sami told police she entered her former home because she “desired a safe place to go.”

The suspect’s 6-year-old son was placed into the custody of a relative after answering questions from social workers, according to the Philadelphia Daily News.

Sami was locked up without bail following an arraignment hearing on Monday. She is expected to face criminal charges including two counts of murder in the first degree, criminal trespass, tampering with physical evidence, and endangering the welfare of a child.
