Good Samaritan Killed Chasing Down Assailant Police say he went after man who stabbed woman, stole her purse By John Johnson, Newser Staff Posted May 1, 2014 1:45 PM CDT 65 comments Comments (Shutterstock) (Newser) – A 47-year-old dad is dead after police say he chased down an assailant who robbed and stabbed a woman near Los Angeles. Authorities say the assailant stole a 26-year-old woman's purse in a grocery store parking lot and stabbed her five times in front of her toddler Sunday night. At that point, a stranger named Troy Cansler came to her aid, chased the attacker, and then got fatally stabbed in the ensuing struggle, reports CBS LA. The woman did not suffer life-threatening injuries, and for that she thanks her savior. "I spoke to his mother today, and I said thank you for raising someone who would put their life on the line,” Krystina Hanrahan tells KTLA-TV. Police arrested Vincent DeLeon, 26, and charged him with murder and attempted murder. Says Cansler's 12-year-old daughter: "I'm very proud. He was everything I could ask for in a dad."
