Police determined the woman, Diane Capitanich, 69, of Vacaville, died from a single gunshot wound to the head.

During their investigation, detectives concluded that Capitanich’s son, Eric, assisted in her suicide at her request.

Eric Capitanich was a Vacaville resident at the time of this incident, but moved to Fairfield prior to his arrest.

The investigation continued for several weeks, and Capitanich was arrested on January 6 on charges of aiding and abetting a suicide (401 PC) and booked into Solano County Jail.

Vacaville police Lt. Matt Lydon said investigators determined Capitanich assisted his mother’s suicide at her request, but his mother fired the weapon.

“She had medical issues that created severe pain,” Lydon said. “We don’t believe he is a danger (to the public). He was doing
right by his mom. We’re not looking at a harsh penalty, but we can’t not charge him.”
