Michael C. Chesna of Han­over, a military veteran and Weymouth police sergeant killed in the line of duty, died July 15. He was 42.

He served in the Army with the 187 10th Mountain Division right after 9/11.

He was awarded a Purple Heart.

Mr. Chesna later fulfilled his childhood dream of becoming a police officer with the town of Weymouth.

He was posthumously promoted to sergeant shortly after his death.

Mr. Chesna was a massive sports fan who played basketball in his weekly men’s league.

He followed all the Boston sports teams with a passion and had a particular devotion to New England Patriots Coach Bill Belichick.

He was a collector of bobbleheads, watches, baseball cards and football helmets.

He was smart and generous and most of all loved wrestling with his son Jack and doting on his favorite girl Olivia, who will always remember her dad’s hugs.

Mr. Chesna is survived by his wife, Cynthia “Cindy” (Doran); a daughter, Olivia; a son, Jack; his parents, Maryann “Mimi” P. (McAvoy) and Charles F. of South Weymouth; a brother, Eric S. of Weymouth and many cousins, nieces, nephews, aunts, uncles and extended friends and family.

Visiting hours will be held from 4 p.m. to 8 p.m. tomorrow at St. Mary’s Church, Hanover, where a funeral Mass will be celebrated at 11 a.m. Friday.

Burial will be in Blue Hill Cemetery, Braintree.
