Authorities claim a small plane collided with a house in southern Mississippi on Tuesday night, killing four people.
A residential street in the area was closed for several hours.
The National Transportation Safety Board said Wednesday that it has sent a team of investigators to Hattiesburg, which is located about 80 miles southeast of Jackson and home to the University of Southern Mississippi.
According to Hattiesburg police spokesman Ryan Moore, officials from the Federal Aviation Administration are also on their way to the scene.
Authorities have not stated whether the plane had just departed or was attempting to land at the nearby Hattiesburg Bobby L. Chain Municipal Airport.
