Two sheriff's deputies were shot in southeastern Texas on Tuesday, authorities said.

They were responding to a report of a disturbance involving weapons at a house in a rural area of Liberty County, northeast of Houston, said Hugh Bishop, a spokesman for the Liberty Police Department.

Someone started shooting at the deputies as they arrived at the house just after 5 a.m., he said. That person died of a gunshot wound, but investigators do not know if he shot himself or if a law-enforcement officer shot him, Bishop said.

Deputy Rex Evans, 40, was released from a hospital after being treated for a superficial wound while Deputy Jeremy Marcantel, 33, was shot in the upper part of his body, Bishop said.

Both wounded law-enforcement officers work for the Liberty County Sheriff's Department.

Investigators do not yet know what prompted the shooting, which happened in the Woodland Hills area of Liberty County, just north of the city of Dayton.
