A Lawrence school district worker who suffered a medical emergency Tuesday at work died Thursday in a Kansas City, Kan., hospital.

Stephen R. Topping, 55, had been in critical condition at Kansas University Hospital after bystanders found a district vehicle he had been driving against a curb near Sixth and Maine streets Tuesday afternoon.

Topping had worked for the district for five years in the grounds department. He had lived in Lawrence since 1975 and was known in city music circles for working as an engineer and producer for Eleanor Jessie Recording Studios.

Superintendent Randy Weseman said Topping cared about the quality of his work and was likable.

“He was fun to talk to. He was a great employee for the district. He will be missed,” Weseman said.

Funeral services will be 1:30 p.m. today at Warren-McElwain Mortuary.
