The tributes for Officer Isabel Nazario started Thursday. Nazario's family, friends, and comrades say their final goodbyes on Friday.

"Chuck Cassidy, Steve Liczbinski and now officer Isabel Nazario. You know you could say there's a lot of different ways that a police officer could lose their life out there and this is just traumatic with what we're going through," John McNesby, Fraternal Order of Police, said.

Cassidy and Liczbinski were shot to death but Nazario, 40, died last Friday when investigators said her patrol car was hit by a speeding SUV trying to outrun pursuing police. Andre Butler, 16, was driving and has been charged with numerous crimes, including murder.

"That young man driving that car had no business in that stolen car. He had a troubled history. I'm glad he's charged as an adult and I hope that he gets serious time from the courts," Philadelphia Police Commissioner Charles Ramsey said.

The 18-year veteran of the force was the mother of a 15-year-old daughter. Both her sister and fiancé are also Philadelphia police officers.

Early Friday, the body of Nazario was taken by horse and carriage to the Basilica of Saints Peter and Paul for Friday's viewing and funeral.

Her fellow officers in the narcotics strike force were heartbroken.

"She had a real strong soft spot for the kids in some of the areas that we work in and as you know we work in some of the more economically depressed areas so she had a big heart in that respect," Capt. James Kelly, Narcotics Strike Force, said.

"She was a good worker, a hard worker and very aggressive on the streets," a fellow officer said.

Nazario's other family, the one that wears blue, also turned out in force on Friday.

Her partner, Terry Tull, who was injured in the accident that killed Nazario, would not let his pain prevent him from being there.

The department was unified in its grief and determined to support the family Nazario left behind.

"Your loss is something very few can understand unless they'd been in your shoes," Ramsey said to the family during the funeral.

Outside, the crowd of mourners spilled outside of the basilica, where a JumboTron gave them a view of what was going on inside.

"It's heartbreaking, it's a great loss to the department," said Detective Maggie Castro. "It's a great loss to the family."

They came from all over New Jersey and Pennsylvania.

"We just wanted to let the Nazario family know, and our brother and sister officers know, that they're not in this alone," said Officer James Stewart Jr. of the Newark Police Department in Newark, N.J.

Following the service at the basilica, the procession headed back to the funeral home in Northeast Philadelphia for a committal service.

During this outdoor service, officers performed a 21-gun salute and played the symbolic last call.

Friday's viewing was from 7:30 a.m. until noon at the Cathedral Basilica of Saints Peter and Paul in Center City. The funeral Mass followed at noon.

A trust fund has been set up for Nazario's daughter. Checks should be made out to the Officer Isabel Nazario Family Memorial Trust Fund. Send donations to the Police and Fire Credit Union at 901 Arch Street, Philadelphia, Pa., 19107.
