CHARLESTON, SC (WCIV) -- Charleston police say a 59-year-old woman was found dead inside her home Sunday and her adopted son may be to blame.

Officers tell ABC News 4 Patricia Walker was found shot to death, in her bedroom, in her home on Orange Grove Road in Charleston.

"It didn't add up," said the victim's mother Catherine Brooks. "That's when i decided i was going to Charleston."

Investigators believe Patricia Walker knew the person responsible.

According to officials with CPD, Walker's adopted son, 21-year-old Walker Pinkleton, is a person of interest in her murder.

"Pat thought they could give him a better chance financially in life and they did, they gave him everything. She worshipped the ground he walked on," said Catherine Brooks.

"I always wondered what he was up to because he was always quiet," said neighbor Chris Stafford who knew Patricia Walker.

Walker Pinkleton was named a suspect Sunday night for a motor vehicle theft. The report states officers noticed the Ford Excursion missing when they found the victim's body and a neighbor told them he had seen the son take the SUV.

According to reports, Walker Pinkleton was arrested for grand larceny around 3 a.m. Monday.

Bond was set for Pinkleton Monday at $50,000 for the grand larceny charge. Court documents say the couple's adopted son had drug problems and stole from them in the past.

During his bond hearing, Pinkleton claimed that he is suffering from PTSD and other mental disabilities.{} No family members were at his bond court hearing.
