A computer scan of the body of 23-year-old Mount Carbon Mayor Brandon M. Wentz revealed “some pulmonary congestion,” said Schuylkill County coroner David G. Moylan III.

Moylan would not release details, but said a traditional autopsy would be performed on Friday evening.

“There are a couple of different things that could cause pulmonary congestion,” he said.

Wentz, who turned 23 on Sept. 6, died Thursday morning.

He was pronounced dead at 7:58 a.m. by Schuylkill County Deputy Coroner Albert Barnes.

Scant details are known of the circumstances surrounding Wentz’ death.

Moylan also said routine toxicology tests will be performed by NMS Labs, Willow Grove.

Wentz, then 22, stepped up in February 2016, offering to serve as mayor of the tiny borough of Mount Carbon, home to 90 souls, after the previous mayor resigned.

The man he replaced, Jeffrey J. Dunkel, had been elected mayor at 18 in November 2001. He is believed to have been the youngest person in the United States ever elected to the office.

No one answered the phone at Mount Carbon Borough Hall Thursday afternoon. Efforts to reach borough council members Michelle L. Stephenson, Alice Breslin, and Jennifer Raess were unsuccessful.

A graduate of Pottsville Area High School, Wentz studied writing at Kutztown University.

He did not seek election to a second term in the November general election.
