Project Q Atlanta was first to report this story.

Noxy Cassandra Calderon, whose legal name is Roberto Calderon-Guzman, was shot and killed on Friday, June 22, in her apartment at Peachtree Place Apartments on Peachtree Place Parkway. On Noxy Cassandra Calderon’s Facebook page, she identifies as female.

Carlson said the motive was robbery and that Williams was targeting transsexual sex workers that he sought out on backpage.com. Dunwoody police say they also know of at least one other transsexual person who was allegedly attacked by Williams in DeKalb County and are asking others who are victims to come forward by calling the Det. Jesus Maldonado at 678-382-6925.

“We know of two victims right now. It appears the other victim was robbed on Wednesday prior to our victim. We don’t know why he shot our victim,” Sgt. Carlson said.

The first victim, who is also transsexual, reported to police she was robbed, Carlson said. Carlson said the suspect was using the first victim’s cellphone and the Dunwoody victim was advertising on backpage.com.

“We want to make sure there are no other victims out there,” he said.

There were two other people in the apartment with Noxy Cassandra Calderon when she was shot, Carlson said. They heard the shooting but did not see it and called 911. Noxy Cassandra Calderson was taken to Northside Hospital where she was pronounced dead.

While the motive in the Dundwoody shooting is robbery, Carlson said that currently no items have been found missing in the apartment. This is the city’s first homicide this year.
