HOUSTON - The body of Houston Fire Department Captain "Iron Bill" Dowling arrived in Houston Saturday evening.

Dowling's body arrived at Hobby Airport around 6 p.m.

Crowds gathered at the airport to welcome home the captain. An American flag covered his casket as fellow firefighters, officers, family and friends saluted the hometown hero.

Houston Mayor Sylvester Turner was one of those in the crowd at the airport to say goodbye to Dowling.

"Captain Dowling has endured more than anybody should have to endure," said Executive Assistant HFD Chief Richard Mann. "He absolutely earned the nickname 'Iron Bill'."

The casket was placed in a Houston Fire ambulance and was taken to Klein Funeral Home in Tomball.

Police units led the ambulance and a procession of vehicles from the airport to the funeral home Saturday evening.

Dowling passed away on Tuesday in Colorado due to complications of injuries he sustained while working the deadly 2013 Southwest Inn fire.

The fire on May 31, 2013 killed four other Houston firefighters.

Dowling lost both legs and suffered a brain injury after a roof collapsed on him while he was fighting the five-alarm fire.

His funeral will be held on Wednesday at 10 a.m at Morris Cultural Arts Center at Houston Baptist University. It will be open to the public.
