Doylestown Shooting: Richard Klementovich, off-duty NJ cop, faces attempted homicide charges after standoff with police

(CBS/AP) DOYLESTOWN, Pa. - Richard Klementovich, an off-duty New Jersey police officer arrested at his estranged wife's Philadelphia-area home, now faces 13 counts of attempted homicide following a 10-hour standoff in which he allegedly opened fire with a high-powered rifle.

Investigators are still trying to determine exactly what sparked the standoff in Doylestown involving a Clifton Township, N.J., police officer.

Klementovich, 42, was taken into custody late Sunday night. The standoff started just before 2 p.m. after police were called to the home over a neighborhood dispute.

Authorities say officers were under fire as soon as they arrived at the home. One officer suffered minor injuries from shrapnel.

Officials say Klementovich eventually surrendered to negotiators. He was arraigned early Monday on dozens of charges including aggravated assault.

NJ.com reports that Klementovich is a U.S. Army veteran who served in the Persian Gulf, according to news clips from the 1990s, and that state records reveal he earned $114,560 in 2011.
