"He was a very caring person. He always helped everyone. He was the best father, grandfather and a very good brother. He was my friend," said victim's sister, Josephine.
So far no word on whether they have strong leads on who stabbed Lombardi to death last week.
They left his body in his car just outside his Valencia home on Undine Road. Authorities say three boys out playing found Lombardi's body slumped over in his car.
The victim's sister Josephine says while she doesn't know who killed him she believes a motive could be greed.
"Money, money is the evil. It was for money. Someone knew and we'll get you," said Josephine.
Detectives say that Lombardi repaired and maintained ATMs, however, they haven't disclosed if money had anything to do with the killing.
They have yet to reveal any motive behind the brutal murder.
Family and friends attending the service Tuesday morning described Lombardi as a church going man who was devoted to his family.
They say whoever took his life must pay for the horrible crime.
"My brother was murdered in cold blood. And we want the person or persons who did this to him to be caught. I can't see you, but you can see me right now. I want you to look into my eyes and know that you will be caught," said Josephine.
Authorities are asking for the public's help. If you have any information about this case you are asked to call the L.A. County Sheriff's Homicide Bureau at (323) 890-5500.
