A Pennsylvania man who drove through a crowd Saturday, killing one person and injuring 17 others, then drove across the river and bludgeoned his mother to death.

Adrian Oswaldo Sura Reyes, 24, allegedly drove through the crowd attending a benefit in Berwick for the victims of a house fire earlier this month, as CrimeOnline previously reported.

The Baker family lost 10 members, ranging in age from 5 to 79 in the August 5 fire in Nescopeck, just across the Susquehanna River from Berwick. Three adults escaped the blaze.

The Intoxicology Department Bar & Restaurant was hosting the outdoor benefit for the family.

Police said that after Reyes drove through the benefit crowd, he headed across the river to Nescopeck, where he rammed his mother and then beat her with a hammer. The Luzerne County Coroner’s Office identified her on Sunday as 56-year-old Rosa D. Reyes, the Washington Post said. She was pronounced dead at the scene.

The victims of the car crash in Berwick have not yet been identified. Matt Mattei, spokesman for the Geisinger Medical Center, said the facility treated 15 patients at several of its locations. Eight were still hospitalized on Sunday at the Danville location, five in critical condition and three in fair condition. Four others were treated and released, the Post said.

The Times Leader said that one person was taken to Geisinger Bloomburg, and two were taken to Geisinger Wyoming Valley. An additional person was taken to Berwick Hospital.

The Intoxicology Department announced that it would be “closed until further notice” in a post on its Facebook page.

Sura Reyes was arraigned on two counts of criminal homicide, the Post said.
