Police say 27-year-old Tyler Honeycutt killed himself at the end of a barricade in a Sherman Oaks home last year.
His mother, Liza Stazel, filed a lawsuit with L.A.'s Superior Court last week. She is claiming negligence, saying the L.A. Police Department failed to de-escalate the situation and get her son medical care.
