Man arrested after woman shot inside car in Tredyffrin Township, Pennsylvania, DA says

Authorities in Chester County, Pennsylvania, have arrested a man in connection with the fatal shooting of a woman in Tredyffrin Township over the weekend.

Police said a woman was shot in her car Saturday around 10:45 p.m. in the area of Contention Lane at Old State Road in Berwyn. After she was shot, her car crashed into a pole, Chester County District Attorney Christopher de Barrena-Sarobe said during a press conference Monday. 

The woman was taken to an area hospital, where she died Sunday evening, de Barrena-Sarobe said. 

Steve Jahn, 44, was arrested and charged with murder and related counts for the shooting, de Barrena-Sarobe said. He is currently at Chester County Prison. Court documents say he had been experiencing homelessness.

The DA said investigators believe this was a "random act of violence" and there is no threat to the community. Investigators have not found any connections between the suspect and the victim, de Barrena-Sarobe said.

He declined to share more details about the shooting or the investigation.

"We're just so distraught for this family," he said.

The violence has shaken a normally quiet neighborhood.

"I think a lot of families move here for the school district, and then also because it's a safe neighborhood, so that's why it was so surprising," said Lori Huang of Berwyn.

Jessica Tinneny from Berwyn said she was grateful police made an arrest quickly.

"We were really, you know, feeling very nervous about driving," Tinneny said.

"This has been a terrible 24 hours in Chester County," de Barrena-Sarobe said. 

Pennsylvania State Police Cpl. Timothy O'Connor was shot and killed during a traffic stop across the county in West Caln Township Sunday night.
