Driver who intended to hit someone else killed woman, 70

A deranged driver attempted to run over a man with her car — but only injured her target and killed a 70-year-old Brooklyn woman who was sitting on a chair outside her home instead, authorities said Wednesday.

Brenda Whidbee, 70, was sitting on Thomas S. Boyland Street near Pacific Street in Ocean Hill around 9:20 p.m. Aug. 24 when Layla Adredini — behind the wheel of a 2003 white Ford Explorer — slammed into her, authorities said.

She was rushed to Brookdale University Hospital Medical Center, where she was pronounced dead, authorities said.

Adredini also allegedly struck a 50-year-old man — her intended target — but only ran over his foot, police said.

The man fled after the incident, but investigators have been in touch with him, cops said.

Adredini, who lives about two blocks from the scene, ran off into the victim’s building — but good Samaritans held her until police showed up and arrested her, authorities said.

She was charged with murder and attempted murder, police said.
