A judge denied bond for Lynch on Wednesday. The 22-year-old woman was attacked Monday afternoon while walking in a North Side alley.
Prosecutors allege Lynch, of the 4700 block of South Loomis attacked the woman at knifepoint. Police say surveillance cameras at a gas station captured Lynch inside the same convenience store with the victim.
"As the victim was walking she heard someone behind her when she turned around she observed the defendant walking towards her. The victim tuned back around and defendant grabbed her from behind," Assistant State's Attorney Pierina Infelise said.
Prosecutors also said police found Lynch's fingerprints at the scene, as well as the double-blade knife used in the attack.
"The victim positively identified the knife as the one the ad put against her neck. The defendant was positively identified in a lineup," Infelise said. "A latent print matching the defendant was recovered from the truck parks in the garage. Defendant also made post-Miranda statements admitting to the incident."
Prosecutors said Lynch is a nutritionist and a personal trainer, which was confirmed by the McCormick Tribune YMCA in Logan Square. A supervisor said he is currently out on disability.
Lynch will remain in custody until trial.
