HILLSBOROUGH — The Hillsborough teen who died on Monday had suffered a punch to the head after an argument, Somerset County Prosecutor Geoffrey Soriano said late Tuesday morning.

Jared Colon, 17, a rising senior at Hillsborough High School, was punched on Saturday evening during a verbal argument with another Hillsborough teen, Soriano said. The prosecutor's office said the other teen is now in custody at the Middlesex County Juvenile Detention Center and has been charged with second-degree reckless manslaughter.

UPDATE: Jared's mom: They tell me he didn't suffer

Hillsborough Township Police responded to a medical call on Orchard Drive around 5 p.m. on Saturday, and they found Colon suffering from a head injury, Soriano said. Colon was subsequently airlifted to Robert Wood Johnson University Hospital in New Brunswick for emergency medical treatment, Soriano said.

Detectives from the Hillsborough Township Police Department and the Somerset County Prosecutor's Office Major Crimes Unit responded to the scene to initiate the investigation, Soriano said.

On Monday, Robert Wood Johnson medical staff advised detectives that Colon died, Soriano said.

A person close to Colon, reached by NJ.com Tuesday, described him as "a great kid" who was "always very active, mechanically inclined, outgoing and smart." The person asked not to be identified.

Colon loved dirt biking, riding quads and fishing, and had many photos of himself holding big catches, she said.

She added that Colon had "two amazing parents who cared about him." He is survived by his parents and two older sisters, she said.

"He was also extremely loving and very loved by everyone he touched," she said. "No one could imagine this happening, his life being taken away too young. But Jared would want the entire world to know he is in a better place."

Hillsborough High School posted a message about Colon's passing on the school website Tuesday morning, though by the afternoon, the notice was removed.

"HHS offers sincerest condolences to Jared's family and friends, as well as to all members of the HHS family who share in this loss," the post said.

The high school offered counseling for students Tuesday from 9 a.m. to 1 p.m.

Several students who appear to have known Colon have tweeted their condolences using the hashtag #ripjared.

"It's just not fair that anyone should have to have life torn from them before they even get the chance to live it," Twitter user Dina_Ragab17 wrote Monday.
