WILLIAMSON, W.Va. -- A memorial service is set for Thursday for a Mingo County EMT who died after becoming ill on the job.

The service for 35-year-old Chris Staggs of Lenore will be held at the Williamson Field House. A visitation will be held there Wednesday.

Co-worker and paramedic L.C. Blankenship says Staggs became ill behind the wheel of a STAT medical services ambulance on Saturday. Staggs lost control of the ambulance, which crashed into the back of a house.

Paramedic Joey Carey, who is Staggs' brother-in-law, says it appears Staggs suffered a seizure.

Media outlets report Staggs later was pronounced dead at Williamson Memorial Hospital.
