Sergeant Edwin Hosli, a ten-year veteran of the New Orleans Police Department, was shot by a sniper while responding to a warehouse alarm on December 31, 1972. He and his canine partner had been called to the scene after the same gunman had murdered Cadet Alfred Harrell. As Hosli entered one of the warehouses, the sniper opened fire and struck him.

The gunman, identified as Mark Essex, fled and triggered a city-wide manhunt that ended in a deadly siege at a Howard Johnson’s hotel on January 7, 1973; during that standoff Essex killed Deputy Superintendent Louis Sirgo, Patrolman Paul Persigo, and Patrolman Philip Coleman before officers engaged and killed him. Sergeant Hosli survived for two months after being wounded but succumbed to his gunshot injuries on March 5, 1973. He was survived by his wife and four children.
