Authorities say a longtime employee of a Florida trucking company killed himself after fatally shooting his former boss and a coworker and wounding two others.

A news release from the Union County Sheriff's Office says gunman Hubert Allen Jr. drove to several locations Saturday morning and shot the four men. Three of them were Allen's former co-workers at Pritchett Trucking Inc., and the fourth was company owner Marvin Pritchett.

The sheriff's office says the gunman fatally shot Pritchett and Rolando Gonzalez-Delgado.

One of the wounded men was in critical condition and the other was in good condition.

Authorities say the 72-year-old Allen returned to his home in North Florida's Lake Butler and fatally shot himself.

Investigators declined to discuss a motive. Messages left seeking further comment from the sheriff's office weren't immediately returned.
