KALAMAZOO (WKZO) -- What caused the fire that killed three toddlers at Interfaith Apartments last week?

Sources say that a burner was left on the stove, apparently something was cooking and they believe that one of the unsupervised children may have used the burner to light something else, touching off the fatal conflagration.

More details are expected to be released later this afternoon.

KALAMAZOO (WKZO) -- Funeral services have been set for this weekend for the three toddlers who died in that fire at the Interfaith Apartments last week. What we don't know is whether 3-year-old twins Tevin and Te’Niya Williams and their 1-year-old half-sister Ty’onna Henderson had been left at home alone.

Visitation will take place from 5 to 7 p.m. Friday at the Whitley Funeral Home. Funeral services will be held Saturday at noon at Mt. Zion Baptist Church.
