A dispute over money and personal items between a Church Hill man and his ex-girlfriend turned violent late Wednesday, according to police.

Police Chief Mark Johnson said four individuals are now charged in the home invasion case that took place at a residence on Shelby Avenue.

Alicia Cassidy, 33, Penny Smallwood, 55, and brothers Daniel McGuire, 34, and Nickolas McGuire, 36, all of Kingsport, are all charged with aggravated burglary, especially aggravated robbery, theft over $1,000 and felony vandalism, Johnson's report said.

The four came to the home of Robert Bang, who allowed his ex-girlfriend into the residence to retrieve some of her personal items. Bang told police that Cassidy then opened the backdoor to let the McGuire brothers in and the attack began with the men hitting and kicking the victim.

Police said Bang was seriously injured in the incident with possible broken bones in his face and ribs.

"(Daniel and Nickolas McGuire) also threatened Bang with knives and threatened to come back and kill him if he notified law enforcement," the report said.

The two men destroyed Bang's cell phone and computer before they left, police said. A guitar, $400 in cash and a GPS unit were also taken during the invasion.

Smallwood and Cassidy were stopped by police in the vehicle minutes later and taken into custody. The brothers were apprehended at Cloud Apartments in Kingsport early Thursday morning, Johnson said.
