Atlanta, Georgia (CNN) -- Police in Dunwoody, Georgia, have arrested a man in the killing of a father outside his 2-year-old son's day care center.
Hemy Zvi Neuman, 48, is charged with murder in the death of Russell "Rusty" Sneiderman on November 18. Sneiderman was shot multiple times in the parking lot of Dunwoody Prep after dropping off his son, in what police have described as an apparent "cold and calculated murder."
Neuman is scheduled to make his first court appearance Wednesday in DeKalb County Magistrates Court.
Police have not given a possible motive. The investigation is ongoing, police said.
Witnesses to the shooting told police a man came up from behind Sneiderman, opened fire, and shot him multiple times. They said the shooter then got away in a silver minivan that didn't have a license plate.
Sneiderman's killing shocked and perplexed many in the community. The married father of two "was murdered. No one should ever have to face that," said his brother Steven Sneiderman at the time. "Our family has been devastated. My niece and nephew will never know their father. My sister-in-law has had an entire lifetime of dreams ripped from her. Our whole family has lost its brightest light, and we don't know why."
The family offered a $10,000 reward for information leading to an arrest.
Sneiderman, 36, was a Cleveland, Ohio, native, a Harvard MBA graduate, and an active volunteer with the Georgia chapter of the Cystic Fibrosis Foundation, CNN affiliate WSB reported.
A week before his death, police said, Sneiderman called police to report a suspicious person behind his house, WSB reported.
Hemy Neuman's Facebook page shows a picture of him smiling with his arms around three children who appear to be teenagers. It says he has worked at General Electric and studied at the Georgia Institute of Technology. His LinkedIn page says he is an operations and quality manager at General Electric.
Neuman has not made a public statement since the arrest.
