The NYPD is expected to announce the promotion of fallen police officer Omar Edwards to the rank of detective later this morning, as family and friends gather to say their final goodbyes.

The posthumous honor will more than double Edwards' salary, entitling his family to better death benefits.

The news came as mourners poured into Brooklyn's Woodward Funeral Home for the second day of wake services on Wednesday.

Some waited in line for more than an hour to honor the devoted father, husband and police officer who touched the lives of so many.

Reverend Christopher Coleman officiated the wake and says he was overwhelmed by the outpouring of love for officer Edwards.

"It was sad. It was sad but there's hope," said Coleman.

On Tuesday, Police Commissioner Ray Kelly, along with city and state politicians paid their respects to Edwards' family.

His funeral will be held this morning at Our Lady of Victory Church.

Edwards was shot and killed Thursday night by fellow Officer Andrew Dunton. Edwards was off duty, dressed in street clothes, and had his gun drawn while chasing a man who he had spotted breaking in to his car.

The Manhattan district attorney's office is now investigating the incident. District Attorney Robert Morgenthau said today that he is confident his office can investigate the shooting fairly.

In the wake of the Officer Edwards shooting, the New York City Police Department has reworked training exercises designed to better prepare police officers for interactions with armed undercover and plainclothes officers.

"We attempt to simulate that as closely and realistically as possible, but in the real world there's more civilians, there's cars driving by, there's people hanging out windows, so it's a very difficult situation," said NYPD Firearms and Tactics instructor Anthony Maida.

Department officials have also released a new training video called "Preventing Friendly Fire."

The revamped eight-minute video will be shown to all NYPD recruits.

The NYPD says it began showing it to all of its officers during roll call and will continue to do so for the next 10 roll calls.

The video features testimonials from officers who have had confrontations with other officers.
