A dispute between Jersey Shore neighbors ended Monday with a husband and wife hospitalized with critical injuries and another man dead from an apparent self-inflicted gunshot wound.

The husband and wife shot by their neighbor, who later took his own life following a standoff with police, remain hospitalized, Ocean County authorities said Wednesday. The couple were shot by John Adamo, 54, of the Bayville section of Berkeley Township, on Monday afternoon, Ocean County Prosecutor’s Office spokesman Bryan Huntenburg said.

A husband and wife were gunned down outside their New Jersey home by a neighbor, who later died by suicide following an hours-long standoff with law enforcement.

Authorities are investigating the case of a neighbor who allegedly shot a husband and wife, then retreated to his home and took his own life in a two-and-a-half-hour standoff that ended with SWAT blasting open his front door.
