APPLETON (WLUK) -- Three people are behind bars and a fourth is being investigated in connection with vandalism at construction sites across the Fox Valley as well as fires that damaged elevators in two downtown Appleton parking ramps.
Officers from the Appleton, Grand Chute and Fox Valley Metro police departments have been working on the case for more than a week. Wednesday morning, they arrested Kevin H. Peterson, 18; Brandon G.S. Fossum, 17; both of Appleton; and a juvenile. Another juvenile is being investigated but has not been arrested.
None have been formally charged and will not appear in court Wednesday as Outagamie County courts are closed because of the extreme cold weather.
The investigation started earlier this month when fires damaged elevators in downtown Appleton's Yellow and Green parking ramps. The fire in the Yellow Ramp caused both of the ramp's elevators to close completely -- one indefinitely and the other for at least several weeks.
"It sounds like there may be some other cases that were involved as well that we haven't completely connected to this as well," said Officer Meghan Cash with the Appleton Police Department.
Then, last week, extensive damage was discovered at the construction sites of the Fox Cities Champion Center in Grand Chute, a house being built by Fox Valley Technical College students in Appleton and an apartment building in Little Chute.
"It appears that unknown individuals at that time utilized construction equipment," Lt. Mark Wery with the Fox Valley metro Police Department explained.
FOX 11 asked officers if any of the suspect had any link to a construction company.
"There is no tie; it is a completely random act by these individuals," Wery said. "It was a group of young adults and juveniles who appeared to be bored and were looking for something to do."
Damage estimates have not been made available.
Editor's note: Based on information from the investigating police departments, a previous version of this story indicated four people were arrested. Police now say only three have been arrested and a fourth is being investigated.
