PROVIDENCE, R.I. -- William Kelly sat in a driving rain outside Grace Church on Sunday, waiting to hear the bells toll for his niece, the latest victim of one of the country's deadliest nightclub fires.

"I keep asking the Lord, 'Why?'" said Kelly, 57. "She was such a sweetheart."

Across Rhode Island and Massachusetts on Sunday, church bells pealed 98 times, once for each person killed in the Feb. 20 inferno at The Station nightclub and for the two who later died of their burns. Kelly's niece, Kelly Viera, died in a hospital Saturday.

"We thought she was in for a long, hard grind," he said, fighting back tears. His 40-year-old niece, who lived in Warwick, was married and had two daughters, he said.

Viera and her husband, Scott, were among more than 300 people who had packed into The Station in West Warwick that night to hear the '80s heavy metal band Great White.

Sparks from display

Fire investigators believe sparks from the band's pyrotechnic display ignited the nightclub's soundproofing material, triggering a fire that swept through the one-story wooden building in minutes as panicked concertgoers tried to flee.

Scott Viera escaped, but his wife was severely burned. "He's beating himself up because he managed to get out and she didn't," Kelly said.

On Sunday, 51 people injured in the fire remained hospitalized in Rhode Island and Massachusetts, including 33 in critical condition.

A grand jury is investigating the blaze. No charges have been filed.

Officials in West Warwick, where the club was located, were expected to release documents today related to the club's history that could include building and fire inspections. The club had passed a fire inspection in December but wasn't required to have sprinklers.

Gov. Don Carcieri asked that all Rhode Islanders pause Sunday "to remember those who have suffered physically and emotionally" following the blaze.

Massachusetts Gov. Mitt Romney, asked residents there to observe a moment of silence, said the lives lost will "remain forever in our hearts."
