Semi Crashes into Kentucky Firefighters Responding to Vehicle Fire

A mother and her son, both firefighters, were in the "mop up" phase of putting out a vehicle fire along a busy interstate when semitrailer slammed into their fire truck early Wednesday, killing the son and injuring his mother, police said.

Jonathan French, 25, was killed and his mother, Lisa French, was taken to a hospital where she was in serious condition, Kentucky State Police Trooper Jeff Gregory said.

Firefighting ran in the French family. Jonathan French had volunteered for the Glendale Fire Department for about five years. Lisa French had been there for about seven years. Her brother is the agency’s fire chief.
