"He is my best friend and now he’s gone," said family friend Rick Naval.

Walker has been arrested on suspicion of two counts of felony vehicular manslaughter and one count of reckless driving causing fatal injuries.

For Naval, hearing the news Walker was arrested and faces charges brought tears to his eyes.

"Jim was very good person, very hard working, always trying to earn something for his family," Naval told FOX40.

While Naval works to heal he hopes for justice for the friend, father and husband the family will have to lay to rest. A GoFundMe has been set up to help his family.

Donations can also be sent to a memorial fund set up by CAHP Credit Union for Officer Griess' wife and three children.

Walker will be arraigned Thursday in Solano County. He is being held in Solano County Jail on $90,000 bond.
