Concord — The state fire marshal has recommended that negligent homicide charges be brought against the operator of a circus tent that collapsed last year in Lancaster, N.H, killing two people.

Bill Degnan said Tuesday he recommended felonies and misdemeanors to Coos County attorney John McCormick, who would determine which charges to bring before a grand jury. A message left for him was not returned.

Forty-one-year-old Robert Young, and his 6-year-old daughter, Annabelle, of Concord, Vt., died Aug. 3, 2015, when a storm blew through the Lancaster Fairgrounds, toppling the tent just minutes after about 100 people had settled in for a show. Fifty people were injured.

Walker International Events, of Sarasota, Fla., has contested fines proposed by federal safety officials for the collapse. A listed number is no longer in service.
