"My dad was a very hard-working man, a very happy person," said Paiz's daughter, Lillian, as she wept.
Family members of 54-year-old Paiz said he was a loving husband, father and grandfather who worked long hours, six days a week at two jobs to provide for those he loved.
"This is really painful," Paiz said. "The person who has done this left emptiness in our hearts."
Detectives said Paiz left a family function sometime after midnight, parked his car outside his home and before he could get out of it, someone shot him multiple times, leaving him in his car to die. Investigators said several hours later a family member found him in his car dead.
"We don't know why someone would want to do something to him like this," Paiz said. "He had a lot of friends, and not enemies that we knew."
"At this time, the motive for this homicide is unknown," said Capt. William Hart of the Los Angeles Police Department. "Thanks to Councilman Herb Wesson and the entire L.A. City Council, a $50,000 reward has been allocated for information leading to the arrest and conviction to Mr. Paiz's killer."
Detectives said people in the neighborhood reported hearing what they thought were firecrackers going off when Paiz was gunned down. They said that no one witnessed the murder.
"All we want, if somebody knows anything, please just call so we can find this person," Paiz said.
Anyone with information is urged to call the LAPD at (877) 527-3247.
