What Happened

Trooper Philip Lamonaco was shot and killed during a traffic stop in Knowlton Township on Interstate 80. The incident occurred when he stopped two members of a radical environmental group known as the United Freedom Front on I-80. The suspects robbed banks to fund their radical operations, which included bombing energy sites. Trooper Lamonaco had disarmed one suspect when the other opened fire hitting him nine times. Trooper Lamonaco managed to return fire, wounding the shooter. Trooper Lamonaco was found face down in the snow by a passing motorist and died in a hospital a short time later. The suspect's bullet-riddled car was found six miles away, along with the blood stains of the shooter and both suspects' fingerprints. The shooter was apprehended, convicted of murder and several bombings, and sentenced to death. He died in prison in 2005. The other suspect was apprehended on April 24, 1985, in Norfolk, Virginia.

In tribute

I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.

Trooper II Lamonaco gave the New Jersey State Police 11 years.

Thank you for your service to the people of New Jersey, and for your service before it. Gone but never to be forgotten.

Rest easy, brother.

— S. Vincent Anthony, U.S. Army 1985-1993
