A Houston man was killed in a single-vehicle crash late Monday after the vehicle’s driver, suspected of being drunk, veered off an Interstate 10 service road and crashed into a ditch embankment, State Police said.

Edwin Johnson, 53, was pronounced dead at the scene near the eastbound Iota and Estherwood exit, State Police said in a news release.

The driver of the vehicle, 27-year-old Shameka Semere, of Houston, had a blood-alcohol level more than twice the legal limit, State Police said. In Louisiana, a blood-alcohol content of 0.08 percent is considered presumptive evidence of drunken driving. She was booked into the Acadia Parish jail on counts of vehicular homicide and careless operation,

Semere, who had her seat belt on, was driving a 1997 Chrysler van east on the I-10 service road when she “failed to negotiate a left-hand curve, ran off of the roadway and struck a ditch embankment,” the release stated.

Johnson was not wearing a seat belt and suffered fatal injuries, State Police said.

Semere remained in jail Tuesday morning. Bail had not been set.
