Authorities excavating yard of suspect in New York’s Gilgo Beach killings

Yard of Long Island's Rex Heuermann - held in connection to the deaths of four people - is being dug up by investigators

Investigators have been digging in the yard at the Long Island home of Rex Heuermann, who was charged earlier this month with killing at least three women and burying their remains on a remote stretch of beach highway.

The 14 July arrest of Heuermann, a 59-year-old architect, marked a stunning breakthrough in the long-stalled cold case that first drew headlines in 2010, when police began searching for a missing woman, Shannon Gilbert, near Long Island's Gilgo Beach.
