Tammy Flowers, the 36-year-old Berkeley County woman investigators say was shot to death by her estranged husband Wednesday, worked several jobs to support two nieces she was raising as her own.

She used art to help intellectually disabled people develop job skills at Berkeley Citizens, a nonprofit, for the last five years. It's the kind of work people do because they are interested in something more than a paycheck, Executive Director Alice Shook said.

"She was such a warm and caring person," Shook said. "We are just devastated. We are still in shock."

Thursday afternoon, a picture of Jesus, plastic flowers and candles sat outside the door where Flowers' body was found at her house on Elmwood Place.

"It's sad," a neighbor who did not want to give her name said. "She worked hard for her nieces. She had her whole life ahead of her."

Her husband, who was captured in Maryland on Thursday morning, is another story.

Darryll Flowers, also 36, spent five years in a New York prison after he was sentenced for first-degree robbery in 1996 in the Brooklyn area. A background check doesn't show any place of employment for him.

He was captured in a stolen Ford Explorer, according to investigators. He cut his wrist and throat with a box cutter as troopers approached the vehicle, but the injuries are not considering life-threatening, according to Sgt. Marc Black of the Maryland State Police.

Flowers will be booked into a jail in Maryland when he gets out of the hospital, then transferred back to Berkeley County, sheriff's Maj. Rick Ollic said.

Neighbors said Tammy Flowers also sold Avon and worked at least one other job. A background check lists Kmart as another employer, although it's not clear if she was still working there at the time of her death.

She took in her two nieces after her sister died. They were taken to a hospital in critical condition after being shot Wednesday, according to the Sheriff's Office.

The 15-year-old was in critical condition but improving Thursday afternoon, but the 13-year-old was fighting for her life, investigators said.

Authorities are not releasing the name of the hospital out of safety concerns, Ollic said.

Flowers kept coming back to the house to keep an eye on his wife after they separated, according to several neighbors. After he shot her and the two girls, he fled the scene in a blue Chevrolet Impala, according to Ollic. Flowers abandoned the Impala in Goose Creek and got a friend to give him a ride to Lincolnville, saying his car had broken down, Ollic said. The friend went inside his house and Flowers drove off in his Ford Explorer, according to an incident report.

The Sheriff's Office put out a description of Flowers and the vehicle, and a Maryland state trooper forced him off the road and flattened his tires near Aberdeen, Black said.

This is the latest in at least 13 domestic-related killings in South Carolina in 2014, according to a Post and Courier analysis. It's the second domestic-related killing in Berkeley County in the last month.

There is no record of deputies being sent to the house on Elmwood Place when the couple was living together, sheriff's spokesman Dan Moon said.
