The cause of death is still under investigation.

Authorities say one of the suspects provided a confession.

Witnesses said Keivaun Mann approached the front door of the residence and discharged multiple rounds from a handgun.

The eight people arrested range in age from 32 to 49 and are from Mt. Vernon, Centralia and Bluford.

The unit is designed to address violent crime — particularly firearms-related offenses — and improve overall quality of life in the City of Carbondale.

WCSO has announced that the death is now being investigated as a homicide.

Danny Davis is a convicted felon and is prohibited from possessing firearms.

This conviction stems from a previous investigation into the death of 57-year-old Patrick Williamson this past spring.

David Mosbacker was wanted on outstanding arrest warrants in Williamson and Richland counties.

He faces up to 15 years in prison.
