Livermore: Man arrested for allegedly killing his grandmother, stabbing mother

Suspect Tyler Haskell, 35, seized on Vasco Road Wednesday

A woman who allegedly was fatally stabbed by her grandson in Livermore on Wednesday night was identified by police today as 85-year-old Joan Lininger.

Police say that Tyler Haskell, 35, stabbed Lininger and his mother, 62-year-old Karla Haskell, with a kitchen knife at a residence in the 5300 block of Hillflower Drive at 7:38 p.m. on Wednesday.

Lininger succumbed to her injuries at the scene and Karla Haskell was treated for a laceration to her arm at a local hospital and later released, according to police.

Police said Tyler Haskell left the residence before officers arrived but a short time later officers found him a mile away, in the 1300 block of North Vasco Road, where he was arrested without incident.

Police said they don't know the motive for the stabbing but said Haskell reportedly suffers from various mental illnesses.

Livermore police spokesman Ryan Sanchez said investigators will submit their report on the incident to the Alameda County District Attorney's Office on Monday so that prosecutors can decide about filing charges against Haskell.

Anyone with information about this incident is asked to call Livermore police at 371-4777.
