PISCATAWAY - Police are learning to combat suicide by giving each other emotional backup with a program called Cop 2 Cop, which tracks officer suicides in New Jersey.

Cop 2 Cop has seen the number of suicides climb steadily in recent years. Last year, 13 officers took their own lives, while four died in the line of duty.

Cop 2 Cop hotlines are staffed by retired officers, who say they've talked nearly 190 cops out of killing themselves. They are now trying to expand that support into the state's police forces, offering training in suicide prevention to officers themselves, so they can spot a troubled colleague.
