A Houston-area firefighter is killed when his bicycle collided with a landscape trailer. 



Investigators with the Harris County Precinct 5 Constable’s office say William "Mark" Braswell was airlifted to Memorial Hermann Texas Trauma Institute after he crashed into the trailer in a Cypress neighborhood.  He later died of his injuries.



Braswell was a 20-year veteran of the Houston Fire Department; he was a captain at Station 6 in the Heights.  He is survived by his wife and two daughters.
