A house fire Saturday night meant a total loss for a Brevard military family. Nicole McCarthy is a Satellite Beach Scorpions Youth Football and Cheer League coach. Her husband is an Air Force reservist. The couple has two children and two dogs. Now, their family is living with friends after flames destroyed their home in the Deer Lakes neighborhood near the Pineda Causeway this past weekend while they all were out to dinner. So far, investigators have not been able to figure out what started the fire.
