Margaret Nicastro, who is already mourning the loss of a granddaughter in the Rhode Island nightclub fire, was told of another family tragedy Friday morning: that her great-granddaughter had died.

Jennifer N. Snyder, 18, of 8118 E. Liberty St., Hubbard, died in a one-car accident Thursday in Shenango Township.

"It's taken a toll on me," said Mrs. Nicastro, of Sharon. "I'm not over the first one yet. This one I took really bad. This is just too much."

Mrs. Nicastro's granddaughter, Donna Mitchell, 29, of Fall River, Mass., was among the 99 people who died in a fire at The Station Feb. 20 in West Warwick, R.I.

Miss Snyder's car was southbound on state Route 18 and she apparently lost control on the snow-covered road, said police, who were called at 12:18 p.m.

The car slid sideways and hit a culvert and then a tree on the driver's side, police said, adding the car spun around the tree.

Miss Snyder was pronounced dead at 1:11 p.m. by Mercer County Deputy Coroner Cris Loutzenhiser, Greenville. He ruled the death accidental.

The accident was caused by a combination of road conditions, excessive speed and faulty tires, Police Chief Ronald Preston said.

"Any one of those alone could have caused the accident, but all three together proved fatal," Preston said.

Mrs. Nicastro said Miss Snyder was on her way to Westminster College, New Wilmington, where she was a freshman.

Miss Snyder was talking of studying child psychology or education, Mrs. Nicastro said.

"She was a very lovable person," Mrs. Nicastro said. "A faithful church-goer. A very pleasant person. She was engaged to be married in a couple of years."

Miss Snyder, a member of Hubbard Church of the Nazarene, was engaged to Brandon Wood.

Miss Snyder was the daughter of Donald W. and Marcy Snyder of Hubbard, who had been the bearers of bad news about Ms. Mitchell.

"They came over to let me know about Donna," Ms. Nicastro said.

Ms. Nicastro said she broke down before she was even told that her great-granddaughter had died. She said she could tell by the faces of the family members who visited her Friday that something terrible had happened.

"I was in no shape today," she said. "Nobody left my side all day."

By nightfall, she was ready to be left alone.

"I need to be by myself a little bit," she said. "But, if I need someone, I know who to call."

Mrs. Nicastro said she last saw Miss Snyder about four weeks ago, when her great-granddaughter picked up some medication for her.

While Miss Snyder was busy with her college studies and working as a cashier at Wal-Mart in Hermitage, "We had a good relationship," Mrs. Nicastro said.
