The Alton Police Department said officers first responded Monday to the area of College Avenue in Alton after a report of an aggravated battery involving a 16-year-old female victim. The victim reported that an adult male approached her while she was walking in a public area near a local school and made unwanted physical contact “of an inappropriate nature,” police said.
Alton Police said officers quickly located and identified the suspect based on information provided by the victim. Raymond Lee Dunnigan, 57, of Alton, was arrested and charged with Aggravated Battery, a Class 3 Felony. Dunnigan was remanded to the Madison County Jail.
Later that same day, Alton Police officers responded to a retail business on Homer Adams Parkway following a report of an aggravated battery involving a 15-year-old female victim. Alton Police said the victim reported that an adult male had deliberately made unwanted and inappropriate physical contact with her inside the store on two separate occasions before fleeing the business.
Through a thorough investigation, which included a review of store surveillance footage and coordination with the Troy Police Department, Detectives identified the suspect as Michael S. Lenglet, 45, of Troy, Illinois. Lenglet was subsequently arrested and charged with Aggravated Battery.
The Alton Police Department thanked the Troy Police Department for assistance and said the arrests “demonstrate the department’s commitment to protecting the most vulnerable members of our community.”
“I want to personally recognize the two young victims in these cases for their bravery and quick thinking in immediately reporting these incidents,” Police Chief Jarrett Ford said. “Their courage to speak up not only led to the swift arrest of both suspects but also serves as a powerful example that reporting these crimes makes a difference and helps keep our community safe.”
In a message to parents and guardians, the department said the incidents were “a sobering reminder that predatory behavior can happen anywhere,” including “on a public sidewalk” or “in a retail store,” and urged families to discuss inappropriate contact and personal safety.
All suspects are presumed innocent until proven guilty in a court of law.
