My grandfather was Mack C. Toner & was a LAPD policeman from 10/1/24 to 12/5/44. He was probably in the academy with policeman Costello as they both showed a 10/1/24 start date. Unfortunately my grandfather passed before I was born & I never got to ask him about his years of service. I want the Costello family to remember that policeman Costello will never be forgotten & was a true American hero. RIP my brother in blue.
