Authorities are investigating a shooting at a security company office in southern New Jersey that has left one man dead and another injured.

Moorestown police Lt. Lee Lieber said that the shooting began in the building Monday around 7 a.m. and then moved outside. He said that one victim sustained multiple gunshot wounds, but was conscious when he was airlifted to the hospital.

Lieber says the incident is being investigated as an attempted murder-suicide.

Lieber says that only one of the men had a weapon. He says that armed workers at the company check their weapons in and out.

The office is located in a business park and is less than a mile away from the Moorestown police department building.
