Authorities say an initial investigation has found no evidence that arson caused a northern Indiana house fire that killed four children and two adults.

State police on Thursday identified those killed in Wednesday’s fire near Logansport as members of an extended family. Two other family members survived the blaze.

Those killed were 42-year-old Joseph Huddleston, his 10-year-old daughter, Kadee Huddleston, his 25-year-old stepdaughter, Brandi Vail, and her three children, 3-year-old Swayzee Hite, 1-year-old Rhylie Hite and 3-month-old Marshall Hite.

Joseph Huddleston’s 43-year-old wife, Sheila Huddleston, and his 19-year-old son, Brandon Huddleston, managed to escape as the flames engulfed the home. The pair was taken by ambulance to Logansport Memorial Hospital with non-life threatening injuries, state police said.

Police say the investigation into the fire’s cause is ongoing.

The fire ignited at the residence just before 2 a.m. local time on Wednesday in a rural area of Cass County, about three miles outside the city of Logansport. The two-story home erupted in flames by the time two deputies arrived on scene, according to the Cass County Sheriff’s Department.

One of the deputies tried to gain access to the second story by climbing onto the first-floor roof but he was pushed back by smoke and flames. The roof and second floor collapsed due to the early morning blaze, the sheriff’s department said.
