THE BRONX - Authorities have released video of three men wanted for questioning in connection to Tuesday's deadly shooting of an NYPD officer.

Officer Randolph Holder, 33, was shot and killed in East Harlem. He is the fourth officer to die in the line of duty in the past year.

Two officers were on a roof when they heard and saw three people fire shots at each other near 455 E. 102nd St. and then take off.

Tyrone Howard has already been arrested and charged in Holder's shooting. Howard has had at least 18 prior arrests and was in a drug diversion program as an alternative to incarceration, according to authorities.

The three other men being sought in the case are described as two black men and one Hispanic man.
