The San Francisco Fire Department today begins to mourn the loss of Lieutenant Vincent Perez, who died in the line of duty this morning at a structural fire.
Also critically injured and still struggling to survive is Firefighter/Paramedic Tony Valerio, a person I knew and had the pleasure of working with in my early years with the SFFD.

Thank you for all your comments on Facebook and Twitter, on chat rooms and in the community. We are all still coming to terms with losing Lt Perez and the full extent of what has happened has yet to sink in here where I am.
