Jimmy Hayes has died unexpectedly this week at the age of 31, law enforcement said.

Another athlete shocked the sports industry after Hayes has been found dead at his Milton home on Monday.

Boston College's Twitter account first disclosed the tragic news, sharing an image of the athlete alongside the text "Jimmy Hayes 1989-2021."

"Boston College Hockey is heartbroken over the passing of Jimmy Hayes. Our thoughts and prayers go out to the entire Hayes family," the caption said.

The statement did not reveal further details about his untimely passing, causing people to worry about what really happened to him. However, Boston Globe noted that his death is not considered suspicious.

His wife, Kristen, also posted photos of her and her family at an arcade during their son's birthday. At that time, Hayes still looked fine and doing well.

According to the first responders who went to his home, he was immediately pronounced dead. They noted, though, that there is nothing skeptical about the cause or manner of his death.

His fans and colleagues sent outpouring messages to Hayes and his family as they demand other people to give them the privacy they deserve.

An NHL reporter said, "Until an official cause of death for Jimmy Hayes is made public, let's show some respect and not speculate and post rumors. Put yourself in the shoes of Jimmy's family and friends. Would you want to deal with that right now?

"I'm thinking I have a idea what Jimmy Hayes cause of death is since sudden cardiac arrest sadly is quite common in current and former athletes and a Boston article said he was out celebrating his one child's bday last night," one alleged.
