Dombroski, who was visiting the island for a rugby tour with St. Joe's, was scheduled to leave the island Sunday.
"The Saint Joseph's University community is heartbroken tonight to learn from the Bermuda Police Services (BPS) in Hamilton that student Mark Dombroski has died".
Dombroski was last seen around 12 a.m. Sunday in the vicinity of The Dog House on Front Street.
A Bermuda police spokesman told The Associated Press that authorities found a body in their search for Mark Dombroski.
Mr Dombroski, 19, from Pennsylvania, disappeared on Saturday night. "We thank the citizens of Bermuda". Authorities have been with her family "shoulder-to-shoulder throughout this ordeal", she said.
"We extend our heartfelt condolences to the Dombroski family", Howard said during a news conference after the body was found.
Detective Sgt. Jason Smith said there's no evidence Dombroski was drunk, or that alcohol played a role in his disappearance. "He wanted to get back".
He traveled to the island March 15 to compete in the 2018 Ariel Re Bermuda International 7s Rugby Tournament along with 19 other teams. He appeared to be using a cell phone device. The team from Saint Joseph's was among more than 20 taking part.
"Saint Joseph's University is in touch with Mark's family and Bermuda authorities and continues to pray for his safe return".
Bermuda Rugby is offering a $1,000 reward for information regarding Dombroski's whereabouts.
Monday night, after news of his death began to circulate, Archmere Rugby tweeted: "Forever our brother, our friend, and teammate". Investigators had asked for the public's help in finding the St. Joseph's University freshman. The team was scheduled to return to the U.S. later in the day.
