JEANNETTE, Pa. — (WPXI) – The community of Jeannette is grief-stricken after a fire killed a young father and four of his six children Wednesday. Westmoreland County Coroner Tim Carson said Tyler King, 27, Kyson John, 7, Kinzleigh John, 6, Keagan John, 3, and Korbyn John, 1-month, were all killed. The mother and two other children were taken to the hospital but survived. Firefighters say they ran into issues with water from a hydrant. The Municipal Authority of Westmoreland County tells our news partners at Channel 11 they are in charge of the water for the hydrants in Jeannette. They said to their knowledge they work properly and are regularly maintained. These hydrants, according to MAWC, were last checked six to eight months ago. They said there could be a lot of circumstances that led to a water problem. The ATF’s fire investigators are assisting state police and Jeannette Police in this investigation.
