RIVERSIDE (CBSLA) — Police are searching for the hit-and-run driver that killed a 60-year-old grandfather and left his Riverside-area family heartbroken.

Hector Diaz-Andrade had been hanging out with his nephew in Riverside and was going to go home with his son when he was struck by a dark car in the street on March 15.

The family says the driver stopped twice, and Diaz-Andrade’s family say they hope that meant the driver really wanted to do the right thing and stop – but panicked instead.

Pieces of the car were left scattered in the street and investigators determined it was a gray 2014 to 2016 Toyota Scion. It was also spotted on home security video nearby. Police say the vehicle will have significant front-end damage and is missing the passenger-side mirror.
