Authorities say a second person injured during a shooting last week at an East Texas plumbing company has died.

Liberty County Justice of the Peace Ralph Fuller says David Grubbs died at a hospital Saturday after being shot at his brother's business near Cleveland, a city of 8,000 people about 50 miles (80 kilometers) northeast of Houston.

Fuller says the other person killed in the shooting was 61-year-old Toni Kelly, an employee, and that business owner Chris Grubbs was also wounded.

Police have said 65-year-old Pavol Vido shot the three before wounding a sheriff's deputy in a fire fight and taking his own life after evading officers for hours.

Fuller says Chris Grubbs and the deputy, Richard Whitten, continue to be treated for their injuries.
