WAGENER -- After witnessing the shotgun death of her mother, a 7-year-old girl scooped up her baby brother and ran a mile to a neighbor's house for help while the killer went after her aunt and grandmother, authorities and a family member said.

The mother, Tabitha Brown, was holding her 1-year-old son when she was shot as her daughter watched, Brown's brother told the Aiken Standard.

The girl first tried to get her mother's cell phone from her pocket, but there was too much blood, so she scooped up her brother and ran a mile to a neighbor's house to get help, Donald Brown said.

Meanwhile, authorities said, Kenneth Myers was still at the house in Wagener on Saturday evening after killing his wife and Brown's twin sister, 25-year-old Angela Myers, and their mother, 50-year-old Vicki Brown. The sisters were shot once in the head, and Vicki Brown was shot in the leg, chest and head, authorities said.

About seven hours later, Myers' ex-girlfriend, 47-year-old Esther Baldwin, was found dead from a gunshot to the head at her home several miles away in Aiken County.

Deputies said Myers told a friend the names of several people he would kill if he ever snapped. Officers began checking on them, finding Baldwin's body. As they were checking on another person, they spotted Myers in his ex-girlfriend's truck, authorities said.

Myers led officers on a chase that ended back at his wife's home, where he killed himself, investigators said.

Deputies still have not determined what led Myers to begin his shooting spree. His ex-girlfriend's relatives said he had a quick temper, was controlling and threatened her during their seven-year relationship. Myers' criminal record in South Carolina consists only of an open-container charge, a few traffic tickets and a misdemeanor conviction on simple assault, according to a State Law Enforcement Division check.

Myers had an automotive glass repair business and was struggling during the bad economic times, but friends and family said he seemed to be a loving father with a big heart.

Myers' daughter, Alisha Myers, told WRDW-TV that since her father's death she has listened to the final voice mail message he left her, which included him singing "Happy Birthday" to her young son.

"Something had to push him to a point, but nobody knows what it was," she said. "I can't fathom a single idea that would lead my dad to do this."
