FRESNO, Calif. (KSEE/KGPE) — Police have identified the man they believe set a house on fire killing two children and severely burning their mother, a news release from the Fresno Police Department said Wednesday.

Fresno Police announced the arrest of Filimon “Robert” Hurtado, 29. He is accused of setting the fire that killed two children and severely burned their mother on Tuesday.

The news release identified the two children killed in the fire as Calyx Hurtado, 5 months, and Cataleya Hurtado, 18 months. Police say the two children were his nephew and niece, respectively.

Their mother, identified only as a 32-year-old woman, is in the hospital with severe burns and police say she is “fighting for her life.”
