It has been a year since Joe Reynoso found his son Mark, and his son's girlfriend Maria De Santiago shot to death outside their home in Mammoth.
"Every single day I drive by that place where it happened right next to my house. I give myself the sign of the cross twice every.... morning... its tough.. its tough," said Reynoso.
Mark had two sons, and Maria had three.
They worked at the Reynoso family restaurant. Sometimes joe still dreams they're all still working together.
"It's been a very hard year for all of us. Hard to get through the day," said Reynoso.
Mark Reynoso was awaiting trial after a deadly triple fatal crash. Detectives say evidence suggests the shooter wasn't there to rob the couple and detective Joe Bonucci believes this wasn't a random crime.
Detective Joe Bonucci said, "we take pride in doing a good job here at the sheriff's office, and personally I feel like I haven't done that for them."
"We lost a lot, and we have no answers, and honestly I've lost hope," Marcela De Santiago, Maria's sister said.
She said she can't rest knowing her sister's killer is still on the loose.
"I hope they can't sleep. I hope this haunts them and maybe they have some remorse and show up. Turn themselves in."
