Employees in a clinic shared by two Lawrence dentists are trying to recover from the shock of finding a co-worker, a Kansas University student, dead.

An autopsy was performed Wednesday on the body of Benjamin Hartter, 22, Morrill, a KU senior who worked as a dental assistant to Dr. Thomas Rainbolt, 316 Maine.

It will be several weeks before all toxicology test results are known and a specific cause of death can be determined, Lawrence Police Sgt. Mike Pattrick said. No foul play was suspected, he said.

Rainbolt found Hartter about 12:30 p.m. Tuesday lying in the basement at the clinic. Police and Lawrence-Douglas County Fire & Medical were called.

Rainbolt couldn’t be reached for comment Wednesday. Dr. John Wulfkuhle, who works in the same clinic with Rainbolt, said Rainbolt was “quite distraught” over the incident.

Wulfkuhle said he didn’t know how Hartter may have died.

Wulfkuhle described as Hartter as a valued employee. “He got along with everybody real well,” Wulfkuhle said. “He just did a tremendous job.”

Shari Gerling, an office worker for Rainbolt, said the staff was upset over Hartter’s death. She said Hartter had worked for Rainbolt nearly two years.

Hartter was majoring in biochemstry, KU officials said. KU Chancellor Robert Hemenway said the entire university is expressing sorrow and extending condolences to Hartter’s family.

“The tragic death of this talented student is a great loss to the university,” Hemenway said.
