Kenneth Dexter Hawkins, 61, was found dead in the driveway of his home on Biscayne Lake Drive in Jacksonville, Florida, on July 12, 2016. A postal worker discovered him lying in a pool of blood; attempts to revive him failed and he was pronounced dead at the scene. Colleagues remembered Kenneth as a well-known bus driver for the Jacksonville Transportation Authority who greeted passengers with a smile and encouraging words.

Investigators say Kenneth had been mowing his lawn when he was approached by 18-year-old Jamil Ibn Muhammad Thomas, who had known Kenneth through the JTA’s Rosa Parks Transit Station and considered him a father figure. The two went inside, an argument turned physical, and Jamil reportedly grabbed a kitchen knife and stabbed Kenneth multiple times. Kenneth staggered outside and collapsed in the driveway. The motive is described as unclear.

Jamil Ibn Muhammad Thomas was arrested and charged in connection with the stabbing. Does anyone who knew Kenneth or his routines around Biscayne Lake Drive have information that could shed light on what led to that argument?
