Video released in vicious attack on senior citizen at Maywood donut shop

LOS ANGELES -- (KTLA) -- Investigators released surveillance video footage Sunday that shows a man repeatedly plunging a knife into the back of a 63-year-old man during a seemingly random attack at a Maywood donut shop earlier this month.

The stabbing, which detectives are investigating as an attempted murder, took place about 3 p.m. on Feb. 10 at Yum Yum Donuts, at Atlantic Boulevard and Slauson Avenue, the Los Angeles County Sheriff's Department said in a written statement.

The video depicts the victim standing at the counter of the shop as the suspect enters the store and stands behind him, as if waiting in line.

About a minute passes without any apparent interaction between the two men when the suspect suddenly attacks from unsuspecting victim behind, stabbing him three times before running out of the store.
