On February 4, 1991, 21-year-old rookie Philadelphia police officer Daniel Boyle stopped a stolen car in North Philadelphia. The vehicle’s driver, 27-year-old Edward Bracey, exited with a 9mm handgun and fired as Boyle approached. Boyle was struck in the head and died two days later; he had been with the department seven months.

Bracey was captured after an incident in which he fell through a skylight and set himself on fire. He was charged with Boyle’s murder, convicted of first-degree murder in 1992, and sentenced to death. After appeals, a 2014 Philadelphia judge found Bracey to be mentally retarded with an IQ of 74 and significant limits in adaptive behavior, vacating the death sentence; the Pennsylvania Supreme Court upheld that decision in 2015, converting the sentence to life without parole.

What can readers who knew Officer Boyle or witnessed the February 1991 patrol stop share about that night or Boyle’s early months on the force?
