That evidence includes a handwritten note, hotel receipts and a subpoena of information from Victoria Secret.
The evidence list is the third list prosecutors have filed in the case, outlining nearly 7,000 pages of evidence.
Prosecutors told Channel 2 investigative reporter Jodie Fleischer they could not comment on any of it, but the list certainly indicates their focus has honed in on details of the alleged affair and they believe the relationship between Andrea Sneiderman and her husband's accused killer is key to the case.
Hemy Neuman is charged with killing Rusty Sneiderman on Nov. 18 in the parking lot of his son's Dunwoody preschool.
Rusty's father, Don Sneiderman, submitted an email to prosecutors documenting a phone call he had with Andrea Sneiderman on Nov. 18, around the time of the killing.
Documents also showed a neighbor of the Sneidermans reportedly saw a silver van around the home that same day. Witnesses say the gunman drove a silver minivan.
And prosecutors have in evidence a Norcostco brand fake beard in a bag. It is not known if it's the actual fake beard police say Neuman wore at the time of the killing.
Prosecutors subpoenaed records from a website called Gunlistings.org, a website used for gun sales, and possibly where Neuman contacted the man who said he sold him the weapon used in the killing, Fleischer reported.
Prosecutors listed a subpoena issued to Victoria Secret store and a handwritten note from a Hampton Inn in Longmont, Colo., regarding flowers and chocolates.
Hemy Neuman was in Longmont on July 15 and 16, 2010, then flew back to Atlanta but had a Frontier Airlines reservation to return to Colorado July 21, 2010, according to documents.
Andrea Sneiderman's reservation at the same Hampton Inn lasted through July 23, court papers detailed.
One month later, the evidence list cites a reservation for Hemy Neuman at the Embassy Suites in Greenville, S.C. on Aug. 26 and 27. Evidence showed a receipt in Andrea Sneiderman's name for the same hotel on those dates.
Andrea Sneiderman's attorney has repeatedly refused to address allegations of an affair between his client and Hemy Neuman. Neuman was her supervisor at GE Energy. Earlier this month, her attorney said, "No one on this earth wants Neuman convicted more than Andrea Sneiderman does."
