Felony charges expected against man who killed his sister as she left work in Riverside

Prosectors are expected to file felony charges against the Riverside man who shot and killed his sister as she left work last week. 
The shooting happened at around 5 p.m. on Wednesday, Sept. 11 outside of a business in the 6900 block of Jurupa Avenue, according to the Riverside County District Attorney’s Office. 
At that time, Riverside Police Department officers arrived to find 45-year-old Adrienne Johnson dead at the scene. 
On Friday, 51-year-old David Johnson was arrested and booked on suspicion of murder and recklessly discharging a firearm, prosecutors said. 
“David exited his car, shot Adrienne multiple times and fled,” said RPD Public Information Officer Ryan Railsback in a statement. 
During their preliminary investigation, detectives were able to identify David Johnson as the alleged shooter and obtained a warrant for his arrest. He was taken into custody at around 10 a.m. on Friday on Phoenix Avenue, police said. 
They have not yet released information on a motive in the shooting.
