A gunman shot six people at an Arkansas home Saturday, killing a man and a teenager and critically wounding two boys, before fatally shooting a worker at a nearby business, police said.

The suspected gunman was later found dead of a gunshot wound in the driver's seat of a stopped car, Jonesboro police Sgt. Doug Formon said at an evening news conference. It was not immediately clear if the gunshot was self-inflicted.

Formon said a man and a 13-year-old girl were killed Saturday afternoon inside the home in east Jonesboro, Arkansas, where it appeared a family was having a party or gathering.

Four other people were injured and were taken to hospitals in Memphis, Tennessee. Formon said the children, ages 8 and 10, were transported in critical condition.

Police received a 911 call about the shooting at the home around 1:00 p.m. Police responded at 1:22 p.m. to a report of a second shooting at a business near a U.S. highway. Forman said the worker was found shot to death at the site, where construction and lawn work had been ongoing.

Forman said police did not know of a motive as of Saturday evening and that the investigation is ongoing.
