Church shooting suspect waives court appearance again.

He faces charges of homicide murder, felony murder, aggravated assault, murder and possession of a firearm during the commission of a felony in the shooting death of 39-year-old Greg McDowell.

Police combed through Palmer’s apartment Thursday in Clayton County.

Palmer was arrested Wednesday afternoon and charged with the fatal shooting of McDowell at the College Park church founded by televangelist Creflo Dollar. It was the second time Palmer had been charged with shooting a man in a church; he pleaded guilty to shooting a man a decade ago in Baltimore and was committed to a mental health facility there.

Police searched Palmer’s apartment at the Reserve at Garden Lake apartment complex in Riverdale Wednesday night and Thursday morning. They removed several items from the apartment, but it was not immediately clear what they took out.

Resident Hoover Sirmans told the Journal-Constitution he arrived home from his job as an EMT in Coweta County around 11 p.m. Wednesday to find the complex locked down by police. He said he went to a resident’s house to sleep and was able to go back home Thursday morning.

Sirmans said he knew Palmer only slightly, “just a hey-how-ya-doing basis … He seemed like a regular old guy.”

When he found out Palmer had been arrested in connection with the shooting, he said, “‘Wow’ is the only word I could say.”

Palmer calmly walked into a prayer service Wednesday morning and opened fire as 20 to 25 people watched in horror. McDowell fell mortally wounded and Palmer, a former church employee, “left just as calmly” as he entered, Fulton County police spokeswoman Cpl. Kay Lester said.

The suspect left in a black Subaru station wagon and was in the vortex of a massive police search until he was arrested without incident at Lenox Square in Buckhead just before 4 p.m.

Palmer, who resigned from the church in August for personal reasons, had been charged previously with attempted murder. In 2004 he pleaded guilty to assault charges and was deemed “not criminally responsible” and was committed, according to Maryland court records. Other records indicate that shooting occurred in 2001.

Christine Singleterry, Palmer’s former mother-in-law, said Palmer shot a man following an argument at a Baltimore mosque. “He got him to go outside and then shot him in the parking lot,” said Singleterry. She said he served about 18 months in the mental facility and was released. She said the victim remains paralyzed.

Singleterry said her daughter, who is now deceased, divorced Palmer in the 1990s because he was abusive. They had two daughters who are now grown.

“He was mixed up and argumentative,” she said. Family members said he moved to Atlanta several years ago.

Mack Simpson, who is married to Palmer’s sister, was shocked to hear the news. “That’s a shame,” he said. “This is the second time.”

McDowell, a father of two young children, was a member of the church’s production crew and a facilities maintenance manager there, police said.

Karen Webb, who had taken her mother to the church for Bible study, said she was told the victim was shot six times.

“I brought my mother up here to go to church — every Wednesday she attends Bible study. As soon as we get here I’m told someone has been shot,” Webb said. “He was one of the praise leaders.”

Dollar, a popular televangelist, started World Changers Ministries in 1986 with eight members, holding services in the cafeteria of a local elementary school, according to the church’s website. Its campus now occupies 81 acres, with services held in the 8,500-seat World Dome. Dollar is a regular on the Trinity Broadcasting Network.

Attempts to reach Dollar were unsuccessful. Ken Terry, a pastor at the church, called McDowell a “tremendous leader, role model and father.”

He said McDowell had been a longtime member of the church. “He was faithful for a number of years. We have known him for years. Since he was a little kid.” Terry spoke of McDowell’s two sons. “He spent a tremendous amount of time with them. He was the model dad.”

Throughout the afternoon, mourners streamed into McDowell’s home, many carrying food. Marlene Guice, a neighbor, said she saw the victim Wednesday morning while she was in her yard and he was on his way to church. “I waved at him like I always do,” she said.

Guice, who has lived two doors from the McDowells for two years, said she met him while walking her dogs in the neighborhood. “They stayed to themselves, but were very nice.”

McDowell was described as an uplifting man, as evidenced by postings on his Facebook site.

In 2010, McDowell wrote, “One of the most valuable assets we can possess is a positive attitude towards our lives. Your attitude is one of the first things people notice when they come in contact with you. Make it good.”

Another time, he wrote, “Life’s too short not to enjoy it.”
