A Youngsville man charged with killing a Lafayette woman and her stepfather in 2011 will take the stand Thursday in his first-degree murder trial.

Eric Abshire, 53, is accused in the deaths of Lona Carter, 39, and 67-year-old Lemuel Brown at their home on Warren Street in north Lafayette. A neighbor found the two dead, each from a single bullet wound in the head, on the morning of July 27, 2011.

Testimony began Tuesday in the jury trial, with the prosecution expected to call its last witnesses Thursday morning.

Abshire was arrested the same day of the slayings at his Youngsville home at 1100 Langlinais Road. There police found an unmarked bottle filled with Xanax, Brown’s wallet — which was missing from his home — and a pistol with two empty .38-caliber special casings, according to his arrest affidavit. The gun’s other four cylinders were loaded.

Witnesses told police they heard two gunshots go off inside the Warren Street home after Abshire arrived around 6 a.m., according to the affidavit. Abshire was known to frequent the home and was seen there the night before, police said.

Abshire is also charged with possession of Xanax and possession of a firearm in the presence of a controlled dangerous substance. If convicted, he faces a mandatory life sentence on each murder charge, up to five years and a $5,000 find on the possession charge and five to 10 years and up to a $10,000 fine on the gun charge.
