The 18-year veteran died Sunday night of a heart attack less than an hour after returning from a minor fire, authorities said.
Patmon's death came just three days after Capt. Herbert "Herbie" Johnson, a 32-year department veteran, was buried following an emotional funeral attended by hundreds of firefighters and friends. He died Nov. 2 while battling an extra-alarm blaze at a Gage Park residence.
On Wednesday officials announced services for Patmon, with visitation set for Tuesday from 4 p.m. to 9 p.m. at Leak & Sons Funeral Home, 7838 S. Cottage Grove Ave.
The Chicago Fire Department walk-through ceremony will be at 6 p.m.
Firefighters will assemble at 9 a.m. next Wednesday at the Apostolic Church of God, 6320 S. Dorchester Ave., where a wake will be held at 10 a.m. followed by an 11 a.m. funeral service.
Interment will follow at Restvale Cemetery, 11700 S. Laramie St. in Alsip, officials said.
