The man sought in a fatal shooting in the early morning hours on Christmas Eve turned himself in to the Ascension Parish Sheriff’s Office, said Chief Deputy Tony Bacala, of the Sheriff’s Office.

Kevin Sheppard, 23, of Prairieville, with no permanent address, was booked into the Ascension Parish Jail on counts of first-degree murder, attempted first-degree murder, carrying of a firearm by a convicted felon, illegal use of weapons and illegal carrying of weapons, Bacala said. He turned himself in to authorities about 10 a.m. Wednesday.

Sheppard was driving in a car with four other men on Josh Brown Road in Prairieville, where it’s believed they had gone to buy narcotics, about 2 a.m. Wednesday, Bacala said. An argument broke out and Sheppard, who was not directly involved in the argument, allegedly pulled out a handgun and began firing.

One man, Lewis Sanchez, 22, of Denham Springs, was killed, and Joshua Perez, 18, of Gonzales, was seriously wounded, Bacala said. He added that Perez is expected to survive his injuries.

After the shooting, Sheppard and another man who had been in the car, Michael Lomas, left the scene in the white Chevrolet Suburban, Bacala said. He said they left behind the shooting victims and Jacob Perez, the brother of Joshua Perez.

About two hours after the shooting, Lomas was taken to the Sheriff’s Office by his mother to meet with investigators.

The Sheriff’s Office says Sheppard was previously convicted of principal to simple robbery in Lafayette, where he was sentenced in October 2011 to three years of probation.
