BURLINGTON COUNTY, N.J. (CBS) – An overnight barricade situation in Burlington County, New Jersey ended with one man dead and his wife seriously injured.

Officers responded to a home on the 200 block of Roosevelt Avenue in Edgewater Park, just after 1 a.m.

Police set up a two-block perimeter around the home and a state SWAT team arrived to try to communicate with a person believed to be inside.

The SWAT team and a handful of other police cars left the scene without incident at around 3:30 a.m.

Officials say the suspected shooter, identified as 57-year-old Gregory Martin, took his own life, before shooting his wife, identified as 46-year-old Michelle Moses-Martin. The woman was taken to Cooper University Hospital where she remains in critical but stable condition.

Officials say Martin was retired from the New Jersey Department of Corrections and was employed by the township as a school crossing guard.

Investigators plan to release more information later Wednesday.
