There was “continuous communication” between a man accused of killing a Dunwoody businessman and the victim’s wife both before and after the murder, according to an affidavit in the case.

Russell Sneiderman was  shot in the parking lot of a Dunwoody day care Nov. 18. Witnesses described a man shooting Sneiderman from point-blank range and then fleeing in a minivan on Mount Vernon Highway.

Investigators in the case successfully petitioned a judge in February to search the content of e-mails and to track past cell phone calls between Neuman and Sneiderman’s wife, Andrea Sneiderman.

Neuman worked as Andrea Sneiderman’s supervisor at the GE Energy campus in Cobb County before he was arrested.

Neuman also knew Russell Sneiderman, according to published reports in the Atlanta Journal-Constitution. Neuman was among the mourners at Sneiderman’s shiva and the two had met and exchanged e-mails, according to the story.

Meanwhile, information in court documents reveals new details on the case. Neuman arrived early for work the day Russell Sneiderman was killed. He left the office before the slaying and returned after, according to the affidavit.

Neuman rented a silver Kia Sedona the day before the slaying and returned it on Nov. 18, after the slaying had occurred, the search warrant affidavit says.

The man who killed Sneiderman was described by witnesses as having a beard, which was described some witnesses as possibly fake.

After Sneiderman’s rental vehicle was located, it was processed for evidence by crime scene investigators. A synthetic hair was found in the vehicle, according to the affidavit.

Police are focusing on the communications between Neuman and Andrea Sneiderman. Andrea Sneiderman has not been implicated by police in her husband’s death.

After a search, investigators found Andrea Sneiderman’s e-mail address in Neuman’s iPhone and iPad, according to court documents.
