Two NYPD police detectives were shot in the head during an undercover mission to buy illegal guns. Three people are in custody in connection with the deaths.
The detectives were found Monday night lying on a street in Staten Island, both shot in the head. They were the first New York City officers killed on duty since the Sept. 11 terrorism attacks.
The slain detectives had been working on the gun operation for about six months. Their identities were withheld partly because of the risk to other undercover officers.
A $20,000 cash reward for information leading to convictions in the case was offered by COP SHOT, a group of businesses. The police are asking anyone with information about the shootings to call (800) 577-TIPS.
