Dunwoody Police have arrested a 48-year-old man in connection with the killing of Russell 'Rusty' Sneiderman.

Police announced Tuesday night that they arrested Hemy Zvi Neuman, of Buckhead, and charged him with murder in the shooting death of Sneiderman.

Sneiderman, 36, was gunned down on Nov. 18 outside of Dunwoody Prep, a daycare in Dunwoody Village. Sneiderman had just dropped off one of his children at school, when he was shot several times by his assailant. The killer shot Sneiderman multiple times at close range and then fled on Mt. Vernon Road in a silver Dodge Minivan without plates.

Police had a short press conference Tuesday night about the arrest.

"I would like to announce that we have made an arrest in this case," said Sgt. Mike Carlson of the Dunwoody Police Department. He said Neuman is being held without bond in the DeKalb County Jail.

Russell's brother Steven Sneiderman, reached Tuesday night at his home in Ohio,  gave kudos to the department.

"We really appreciate the efforts of the Dunwoody Police Department," he said.

He declined to further comment on the case Tuesday night.

According to Neuman's LinkedIn and Facebook accounts, he is a graduate of Georgia Tech and worked with General Electric in operations.

A background check showed he'd previously lived in Boca Raton, Fla. and New York State. His booking information lists an East Cobb home address. Police confirmed he had lived in that area and recently moved to Buckhead.

Carlson declined to say if and how Neuman and Sneiderman were connected, and declined to answer any further questions about the case, saying it was still under investigation.

Soon after the crime, Dunwoody Police Chief Billy Grogan described the shooting as "a cold and calculated murder," and said it was not a random act.

Sneiderman's friends and family said he did not have any enemies and they appealed to the public to help find the killer.

His family offered a $10,000 reward for information that leads to the arrest and conviction of the killer.

During a November press conference, Steven Sneiderman said he has no idea what would drive someone to kill his brother.

"That's what so hard to understand," he said. "To know my brother was to love my brother."

"He would do anything for anybody," he added. "I can't fathom for a moment what would drive someone to do this. We're just grasping; and we're devastated."

Steven described his brother, a Harvard Business School MBA and an entrepreneur, as extremely generous.

"He wanted the best for all of us," he said at the November press conference. "When people would come to him, his friends, he'd do anything for his friends. That's how he'd get involved in these charities."

Russell, or Rusty as he was known to friends and family, served on many boards, including the Osteogenesis Imperfecta Foundation and the Autism Society of Georgia, and was involved with the Wish for Wendy, which benefits the Cystic Fibrosis Foundation.

Russell was in the process of starting up several companies on his own. He had previously worked for many large companies, either as an employee or a consultant, including JP Morgan.

Carlson said the investigation is ongoing and asked that anyone with information about the case is asked to contact Det. Andrew Thompson at (678)382-6921 or the department's Tipsoft website.
