Two firefighters were fatally shot and a third is seriously injured after investigators say a lone gunman opened fire on fire crews responding to a brush fire on Canfield Mountain Sunday, near Coeur d’ Alene, Idaho.

Kootenai County Fire and Rescue Chief Frank Harwood and Coeur d’Alene Fire Department Battalion Chief John Morrison were identified by fire officials as the fallen firefighters.

The injured firefighter has been identified as Coeur d’Alene Fire Department Dave Tysdal, according to fire officials.

Here’s what we know:

Frank Harwood, 42: During a press conference Monday, Kootenai County Fire and Rescue Chief Christopher Way said Harwood was a member of the agency for 17 years.

He was married, had two children and was a former Army National Guard combat engineer. Harwood was a leader who “did an amazing job” and was well respected, Way added.

John Morrison, 52: Morrison served with the Coeur d’Alene Fire Department for more than 28 years and moved up the ranks in his department from firefighter to battalion chief, according to Coeur d’Alene Fire Chief Tom Greif.

A colleague shared his final memory with Morrison during Monday’s press conference recalling a time when the pair smoked cigars during a rare lull at the fire station.

“We talked about being better fathers, we talked about being better leaders, talked about being better firefighters,” said Gabe Eckert, President of the Coeur d’Alene Firefighter’s union.

“These guys were hard workers. They loved their families,” Eckert added.

Dave Tysdal, 47: An engineer with the Coeur d’Alene Fire Department, Tysdal is recovering after undergoing two surgeries following the attack on firefighters in Idaho on Sunday, according to Fire Chief Tom Greif.

Tysdal has been an engineer with the fire department for 23 years, Grief said.

“We thank everyone for their love and support,” a family statement read by Greif said. “Dave is surrounded by his family, and he is able to open his eyes and the two surgeries have gone well.”
