A 55-year-old Lee County woman called authorities to say her son was threatening her just moments before she fatally shot her son, authorities said Wednesday.

Lee County sheriff's deputies responded at 11:57 a.m. Tuesday to a shooting call in the 200 block of Lee Road 229 in the Smiths Station subdivision of Kaldallen, said sheriff's Capt. Van Jackson. Once on the scene, they found 23-year-old Robert Lee Woods Jr. inside the home with two gunshot wounds to the chest and lower abdomen. He was pronounced dead on the scene.

Jackson said a .38-caliber handgun was found at the scene by responding deputies. Woods' mother, Francine Woods, was at the home when deputies arrived, and authorities quickly learned she had fired the deadly shots.

Jackson said law enforcement officials had been called to the same home at least six times on domestic disturbances dating back to 2011. On Tuesday, Francine Woods called the sheriff's office at 11:20 a.m. to report that her son had called and threatened her, Jackson said. The evidence showed Woods arrived at the home shortly before noon and forced his way into the home just prior to the shooting.

Jackson said Francine Woods is cooperating with investigators, and no charges have yet been filed in connection with the shooting. The slain son's body has been taken to the Alabama Department of Forensics Sciences for autopsy.

The investigation is ongoing. Anyone with additional information is asked to call the Lee County Sheriff's Office at 334-749-5651 or Lee County Crime Stoppers at 1-888-527-7847.
