— UPDATE: Mackenzie Greco has been found safe in Mount Carmel Township.
More information will be posted as it becomes available.
MOUNT CARMEL — Police today continue their search for a teenager whose parents said he went out for a run Monday night and never returned.
He described Mackenzie Greco, the missing 17-year-old from Clearmont Street in Marion Heights, as “endangered.”
Numerous volunteers combed through 20 square miles of rugged terrain Tuesday, continuing a search that began around 8 a.m., Hollenbush said.
Greco reportedly attended cyber school and had no family issues with his parents, Hollenbush said. Greco’s father declined to comment Tuesday.
Greco was an avid cross-country runner and Eagle Scout.
Various people reported seeing Greco on Tuesday, Hollenbush said, but none of those leads were confirmed.
Greco left his home around 7:30 p.m. Monday for a run, Hollenbush said.
Five hours later, his parents called 911 to report him missing.
“At that point, his parents became concerned when they hadn’t heard from him,” Hollenbush said.
Greco was last seen on surveillance video around 9:15 p.m., walking about four miles from his home near a food warehouse at Seventh and Oak Streets in Mount Carmel, Hollenbush said.
Greco does not have any known medical conditions that would have caused him to faint or become incapacitated, Hollenbush said.
Not returning home is something that is extremely out of character for the teen, Hollenbush said.
“This isn’t normal behavior,” he said.
Numerous volunteers — including Greco’s cross-country and track teammates — gathered at Mount Carmel Area High School on Tuesday to search for any sign of Greco, who often ran on the trails behind the school used during cross-country season.
Area businesses pitched in with food for the search parties.
Teammates described Greco as a friendly boy who is shy at first, but outgoing when he’s with friends.
“He’s a good friend,” said Justin Skavery, of Mount Carmel. “He’s a very nice kid, talkative. He’d always be chatting when you ran (with him).”
Much of the team was at the search for Greco, concerned after receiving messages that he had disappeared, Dondre Glasper said.
“I woke up this morning and had a bunch of messages saying he was missing,” he said. “I hope he comes home safely.”
Police, fire and emergency medical personnel from across the Valley were also on hand for the search. By afternoon, helicopters were being used in the search for Greco, according to witnesses.
Volunteers were canvassing any area where Greco might have been running, though the huge expanses of open land — much of it rocky and uneven — made the search slightly difficult, Hollenbush said.
