The headline says "Roswell" but this occurred in Mountain Park, not Roswell. Might be worth updating the headline.
Mountain Park is a separate city from Roswell, complete with its own Mayor and City Council. It is a beautiful town, you feel like you're in a mountain retreat if you drive through it. Congratulations to the citizens that detected the activity!
Mountain Park outsources policing to Roswell which is why Roswell Police would have paid the visit.
