LAPLACE — One local woman was killed and another hospitalized following a collision on Interstate 10, authorities said.

Markesha Williams, 27, of LaPlace died at a local hospital sometime after 12:30 p.m. Friday as a result of injuries suffered in a one-vehicle wreck, Louisiana State Police said. Troop B spokeswoman Trooper Melissa Matey said a second victim in the crash, LaPlace resident Rachelle Jackson, was taken to University Medical Center with critical injuries. As of Tuesday morning, Jackson was listed in serious but stable condition, according to authorities.

Preliminary investigation indicates Williams was driving a 2009 Toyota Camry east on I-10 near Louisiana 3188 when she lost control of the vehicle.

Jackson, 30, was in the front passenger seat, Matey said.

The Camry ran off the road to the right and struck a message board sign pillar before coming to a stop.

Matey said it is unknown if either victim was wearing seat belts, adding Troopers believe excessive speed may be a crash factor.

“The roadway was wet,” Matey said. “I don’t think it was saturated, flooding wet, but there had been a light rain prior to the crash. When anybody is going too fast on a roadway, of course, you can loose traction. Multiple different things can happen when you’re speeding on a wet roadway.”

Impairment is unknown, authorities said, and a standard toxicology test is pending an autopsy.
