A K-9 team searching near Highland Lake northeast of Longmont on Thursday for signs of a missing 42-year-old Boulder man responded to something in the area, and a dive team will return to the lake this weekend to continue the search.

Oswaldo Zapata Reyes — described as a Latino male, 5-foot 6-inches tall, weighing 185 pounds with brown hair and brown eyes — was last seen at his home in the 3500 block of Nottingham Court in Boulder on July 27.

Boulder police Sgt. Rob Bustrum said the search dogs "indicated" at something in the area, so a dive team will return Saturday morning to investigate a corner of the lake near Mead.

"It's something that warrants further search," Bustrum said. "So we're going to take a dive team out there and search a section of the lake and see if there is anything there."

Bustrum said that, other than the dogs reacting, no evidence of Reyes' whereabouts was found.

Boulder police spokeswoman Kim Kobel said investigators were told by acquaintances of Reyes that he recently had been to the lake, so police were searching the area as they continue to look at places Reyes frequented.

"We're just checking all of our leads to see if there is any sign of him," Kobel said.

Police said Reyes' friends, coworkers and family have not heard from him since July 27. All of Reyes' roommates have been interviewed by police, and investigators "have been searching for any clues as to his whereabouts without any success," according to a police news release.
