SANTA ANA, Calif. — The attorney for a former construction worker convicted of murder for killing rookie Los Angeles Angels pitcher Nick Adenhart and two others in a drunken-driving crash is asking the judge for leniency at his sentencing hearing Wednesday.

Attorney Jacqueline Goodman said her client, 24-year-old Andrew Gallo, was “not a monster” but was immature and the product of a broken home. She said his alcohol addiction led him to drink for hours with his stepbrother before blacking out and getting behind the wheel of the family’s minivan.

Gallo was convicted in September of three counts of second-degree murder in the deaths of the 22-year-old Adenhart and his friends, 20-year-old Courtney Stewart and 25-year-old Henry Pearson. A fourth passenger, Jon Wilhite, was severely injured.

Gallo’s blood-alcohol level at the time of the collision was estimated at nearly three times the legal limit when he ran a red light and T-boned Stewart’s car at a Fullerton intersection, prosecutors have said.

Deputy District Attorney Susan Price said in her own court briefings that Gallo should receive consecutive 15-years to life terms for each of the deceased victims, and an additional six years, eight months for injuring Wilhite and for leaving the scene of the collision.
