Federal authorities offered a reward for information about those responsible for igniting a pair of New Mexico wildfires that killed two people and destroyed hundreds of homes in the past week.

The FBI on Saturday offered up to $10,000 for information in connection with the South Fork Fire and Salt Fire in southern New Mexico, which forced thousands to flee.

An agency statement said it was seeking public assistance in identifying the cause of the fires near Ruidoso, New Mexico, that were discovered June 17. The notice also pointedly suggested human hands were to blame, saying the reward was for information leading to the arrest and conviction of “the person or persons responsible for starting the fires.”

The South Fork Fire, which reached 26 square miles (67 square kilometers), was 26% contained on Saturday. The Salt Fire, at 12 square miles (31 square kilometers), was 7% contained as of Saturday morning, according to the National Interagency Fire Center. Full containment was not expected until July 15.
