A fire investigating dog with the St. Clair County Sheriff's Office has lost its fight with cancer, officials said Wednesday.

Sheriff Tim Donnellon said Gunner, a 9 ½-year-old K-9 unit that detected fire accelerants, died from cancer.

Gunner worked for the sheriff's office for eight years, Donnellon said in a statement.

The dog joined the office in 2010 through a grant from the State Farm Insurance Company, the sheriff said. His handler was Lt. Scott Braun.

Donnellon said Gunner and Braun investigated more than 300 suspicious fires across St. Clair County and elsewhere in the state.

"They also appeared many times at events throughout the community, where children and adults all fell in love with the very calm and well-behaved (Gold Labrador)," the sheriff said. "Gunner will be missed by Lt. Braun and his entire St. Clair County Sheriff family."
