Martha Gutierrez has not been located by police, but a vehicle containing evidence of a violent assault has been, according to Chad Gallacinao of the Gilroy Police Department.
A vehicle belonging to Abel Gutierrez, the , was recovered Friday and contained evidence indicating the discharge of a firearm that police believe was used to shoot someone in the vehicle. Police also found a cell phone that family members identified as belonging to Martha, Gallacinao said.
Police are now viewing the call records, as well as Abel's, in an attempt to determine Martha's location.
"She was last seen on Tuesday evening and the [murder-suicide] happened on Wednesday, so we're looking at that 24-hour period to give us locations to start looking for Martha," he said.
Gallacinao said police believe Martha is somewhere in the tri-county area of Santa Cruz, Monterey and Santa Clara. The GPD, he said, has contacted each county's sheriff department and will coordinate specific areas to search once Martha's location is narrowed down.
"We're hoping for the best, but as more time goes on, our hope for her to be found alive dwindles," Gallacinao said.
