WATERBURY, Conn. (AP) A civilian employee of the Waterbury Police Department has been placed on leave while the way she handled a 911 call about the shooting of a food delivery driver is investigated.

Police on Thursday said seven-year department employee Nicole Scarino is on leave.

Two people who worked for a Chinese restaurant were ambushed Tuesday night while making a delivery. Fifty-nine-year-old Helena Vargas was shot in the neck and killed. Her male companion was beaten. Four teenagers face murder charges.

In the 911 call, there appears to be a frustrating language barrier between the caller and the person handling the call. The person handling the call shouts and groans.

Mayor Neil O'Leary tells The Republican-American the person who took the call showed ``a lack of compassion and a lack of professionalism.''
