HOUSTON -- Two firefighters and a cyclist remained hospitalized a day after two fire trucks collided in a Montrose-area intersection, KPRC Local 2 reported.

Eleven people, including nine firefighters, were injured in the collision at the intersection of Dunlavy Street and Westheimer Road on Monday at 10:45 a.m..

A Houston Fire Department pumper truck weighing 42,000 pounds and traveling northbound on Dunlavy Street broadsided an 80,000-pound ladder truck traveling west on Westheimer Road with enough force to lift the ladder truck off the ground.

The ladder truck rolled, hit a woman on a bicycle, snapped a utility pole and landed on top of a car.

The most seriously injured was cyclist Leigh Boone, 29. She was on her way to work when the wreck happened.

Boone is in intensive care at Memorial Hermann Hospital. Her brother, Jeff, said Boone's condition has been up and down, but she seems to be responding to medicine.

Five firefighters on the ladder truck and four on the pumper truck were also injured.

Capt. Michael Mayfield and engineer operator Brian Edwards were in stable condition on Tuesday. They were in the cab of the pumper truck.

"We have two firefighters and they have several fractures to their arms and legs and ribs," Executive Assistant Chief Rick Flanagan said. "It's going to be a long period of recovery."

"They're tired and they're beat up," said Capt. R.J. Powell with HFD Station No. 7.

Powell visited the firefighters Tuesday morning. Both men suffer from broken bones, but were anxious to hear about Boone's condition. Edwards has a broken leg. Mayfield has a broken leg and arm.

"Basically they were both concerned about the lady that was on the bicycle -- the reports I got this morning -- the relief time, that was the first question when they woke up from initial surgeries," Powell said.

The other seven injured firefighters were all treated and released from hospitals.

Police said Tuesday that the pumper truck Edwards was driving had the green light at the intersection.

However, a witness told investigators that the driver of the ladder truck may have run a red light.

Jotika Ramchandi, 48, said she was waiting for the light to turn green on Dunlavy when the accident happened.

She escaped with minor injuries.

"I think she'll be OK, but it remains to be seen what kind of injury she has and treatment that will be necessary," attorney Terry Bryant said.

The signal is equipped with an electronic device called an Opticom, which allows emergency vehicle drivers to control the light from the dashboard.

It is not clear if it was working properly.

"The ladder truck was in the intersection. There are a lot of pieces that still have to be reviewed with this investigation," said Flanagan. "Our units do have the emitters to operate the Opticoms. What the Opticom would do is give the person the right-of-way, or turn a red light to green, to give them access to go through the intersection and have a speedy response time."

Police have not yet interviewed Edwards or the other fire truck driver.

"There are some things we are going to have to look at and probably things that will have to be changed," Flanagan said.

The fire trucks were answering a call of an apartment fire in the 2100 block of San Felipe Street when the collision occurred. Both trucks had lights flashing and sirens blaring.
