A search warrant executed at the home of accused Gilgo Beach serial killer Rex Heuermann has concluded, according to family lawyer Robert Macedonio.

He said the search had concluded for now and appeared to be focused in the home’s basement.

A News 12 source says Macedonio accompanied Heuermann’s daughter inside the home.

In a statement last week, the Suffolk District Attorney's Office said: "As District Attorney Tierney has previously stated, the work of the Gilgo Beach Homicide Task Force is continuing. We do not comment on investigative steps while ongoing."

Heuermann has been charged with murder in the killing of Maureen Brainard-Barnes, Melissa Barthelemy, Megan Waterman and Amber Costello, whose bodies were found buried along the remote beach parkway.
