A Windsor man who was found at fault in the deaths of five people in a 2007 crash on Highway 101 is back in jail after serving about two years in state prison.
Ryan Karr, 31, faces felony domestic violence charges stemming from an incident alleged to have occurred April 30.
He could be sent back to prison if convicted of inflicting corporal injury on a spouse and assault with a deadly weapon causing great bodily injury. He has pleaded not guilty.
Karr was sentenced to four years in prison in 2010 for the rear-end crash north of Santa Rosa that prosecutors said happened when he was under the influence of marijuana.
Jurors convicted him of five counts of felony vehicular manslaughter.
Killed were Edith Carlos Medina, 23, her son, Fernando Flores Carlos, 7, her grandmother, Maria Lopez Camacho, 54, and an aunt, Almadelia Mendera-Basurto, 16, all of Windsor; and an aunt, Carmina Solorio, 23, of Mexico.
Medina's then-4-year-old son, Christian Flores, was pulled from the flames. He suffered burns over 70 percent of his body and lost part of his leg, arm and an ear.
Karr received the minimum sentence and was required to serve just half-time.
