"This happened on a piece of land that has not been developed," Manchester Police Sgt. Dan Rehm tells Patch, although will not say the exact location, he does it is not a park. "We're not going to disclose that because it's too close to the victim's home."
As previously reported by Patch, Rehm said the teenage girl did not consent to the act and DNA evidence was used to link Witkowski to the alleged assault.
Now, police tell Patch that other girls are coming forward in connection to Witkowski's arrest.
"We have received about a dozen phone calls from girls. A few that have either dated him in the past, or a couple who may have actually been attacked by him in the past," Rehm tells Patch. "And we're going to coordinate with other (police) departments in those areas to see if there is enough to initiate reports to take to the prosecutor for review."
Rhem said Witkowski used parks throughout the West County area to meet girls.
"He was meeting girls at parks and striking up relationships with them. And he was also meeting them through Facebook," Rehm said. "One of he main parks that keeps coming up in discussion is Vlasis Park up in Ballwin."
Investigators said Witkowski is in the St. Louis County Jail on $15,000 bond.
"We're just interested in speaking with any other possible victims that might be out there," Rehm previously told Patch. "We believe they would most likely be from the West County area."
