One person was found dead and five others were found suffering from carbon monoxide poisoning at an Edwardsburg residence early Friday morning.

The Cass County Sheriff’s Department is reporting that Andrew A. Weston, 43, of Columbus, Indiana, was found dead in the basement of the residence, which is located in the 66000 block of Indigan Lane in Jefferson Township.

Five family members: Elizabeth Weston-Hammang, 41; David Hammang, 46; Ian, Hammang, 5; Clark Hammang, 5; and Ava Hammang, 3; were discovered suffering from carbon monoxide poisoning. These five family members had been on the first and second floors of the residence at the time of the incident, according to the sheriff’s department.

The Hammang family was transported from the scene to both St. Joseph Medical Center and South Bend Memorial for treatment.

Initially, Cass County Central Dispatch received a call at 5:33 a.m. from a person who said they felt dizzy, short of breath and faint.

Life Care ambulance was dispatched and, upon arrival, found multiple victims suffering from carbon monoxide poisoning in the residence.

A Cass County Medical Examiner Investigator was called to the residence and an autopsy is scheduled/pending to confirm the cause of death for Weston as carbon monoxide poisoning.

Initial investigation indicates that the source of the poisoning may have been from an enclosed pool heating/boiler system. The pool room and equipment room was attached to the basement, near where Weston was found.

Columbus Indiana Police assisted in notifying Andrew Weston’s wife, Jennifer Baxter Weston, of his passing from this incident.

Ontwa/Edwardsburg Fire Department responded to the scene and cleared the residence of the carbon monoxide through fans/venting of the house.

Life Care Ambulance was assisted on scene by Ontwa/Edwardsburg Ambulance and SMCAS Ambulance.

Cass County Animal control assisted by taking the family’s dog to an area veterinary service and is holding the dog for the family to pick up.
