WAKEFIELD — Frigid temperatures hovering in the single digits and a wind chill factor of well below zero might have claimed the life of a 19-year-old man early Saturday morning if not for an intensive police search that included a State Police K-9 named Rocky.

Police received a call just before 2 a.m. Saturday from a frantic Wakefield mother who said that her son, 19, was intoxicated, extremely upset and suicidal.

She also said the young man had fled from her home in the vicinity of Vernon and Water streets while driving a GMC Jimmy SUV at a high rate of speed. He may have been carrying a knife, the mother said.

A search was launched immediately by Sgt. Matthew Maglio and Patrol Officers Matthew Chambers, David Rando and Jonathan Burnham. State Police were also alerted and a request for K-9 assistance was made to find the missing man.

Police were able to “ping” the man’s cell phone, which revealed he was somewhere near the downtown area of Wakefield. Police said the search took about two hours because the area is so widespread, but K-9 Rocky finally located the man sitting under a tree behind a snowbank on the Veterans Memorial Common across from Bryant Street.

In spite of the frigid temperatures and the fact that the man was wearing only a navy blue Massachusetts Maritime sweatshirt, he was found conscious and alert in a snowy area he had dug out, said police. He appeared to have consumed alcohol and also suffered a laceration but police did not say what area of his body was injured.

When approached by police, the man went with them willingly and was transported by Action Ambulance to Lahey Clinic in Burlington for treatment. The two State Troopers assisting in the search were Rocky’s handler Jason Vital and Sean Stowe.

“The outcome could have been a tragedy,” said Wakefield Police Lt. Craig Calabrese. “Every officer, including the K-9, did a great job finding this young man and saving him from a certain death.”
