NORCROSS -- SWAT team activity behind a Norcross elementary school Thursday morning was an unsuccessful attempt to arrest Joseph Tyler Sivonda, the suspect in at least three armed robberies turned sexual assaults.
Gwinnett County police spokesman Cpl. Jake Smith said that the department's SWAT team attempted to serve an arrest warrant Thursday at an apartment at 100 Castor Drive in unincorporated Norcross, just behind Beaver Ridge Elementary School. The warrant was for Sivonda, who was not present and still at large.
Authorities are now asking for help finding him.
The 23-year-old Hispanic male, described as about 5-foot-7 and 130 pounds, is currently facing two counts apiece of armed robbery, aggravated sodomy and rape. Smith said at least three separate, similar incidents have been reported recently.
"We suspect there are more victims that haven't come forward," he said.
A police report from one of the incidents described a grisly M.O.
According to the report, the 20-year-old female victim and her friends ended up at the Bradford Gwinnett Apartments on Castor Drive late Sunday night after an unidentified woman asked for a ride from a nearby gas station. After dropping the woman off, the victim reportedly spotted Sivonda sitting on a set of stairs and asked to use his bathroom.
Once inside an apartment, the victim realized it was empty and attempted to leave. Sivonda then produced a handgun and demanded she hand over her money and take all her clothes off, the report said. Sivonda allegedly took her bag before his eyes turned "evil looking."
"He said, 'In order for you to leave you have to put your clothes back on, perform oral sex ...'" the victim told police. "'If you do that I will put my clothes back on, take your bag, leave and you have to wait (five) minutes before you leave.'"
She did so and Sivonda reportedly fled out a patio door.
Information regarding other alleged incidents was not available Thursday. Jail records show Sivonda spent more than two years in the Gwinnett County jail starting in October 2006, a sentence stemming from several charges of armed robbery.
Anyone with information on Sivonda is asked to call robbery detectives at 770-513-5300 or Crime Stoppers at 404-557-TIPS. Anyone encountering him should call 911.
