A 15-year-old girl became the fifth victim Saturday of a suspected serial killer in Gaffney, S.C., dying less than two days after being shot.

Abby Tyler died Saturday morning at Spartanburg Regional Medical Center, The Gaffney Ledger reported. She was shot in the head by a man who opened fire Thursday on her and her father at his store, Tyler Home Center. Her father, Stephen Tyler, died at the store.

Cherokee County Sheriff Bill Blanton said police have a sketch of the man suspected of killing the Tylers and three other people, WYFF-TV, Greenville, reported.

"Without a doubt, we are confident that the same subject is involved in all the shootings," Blanton said Friday.

Gaffney residents said Tyler's family is well-known in the city.

"They are just as nice as they can be -- the kids and all. It is just unreal," Jane Whisnant, who owns the Country General Grill in Gaffney, told WYFF.

The bodies of two other victims, Hazel Linder, 83, a retired teacher, and her daughter, Gena Linder Parker, were found Wednesday in Linder's home.

The other victim, Kline Cash, a peach farmer, was shot dead last weekend.
