The St Louis Police Department announced Wednesday that they had the suspected shooter, 18-year-old Mark L Haywood, in custody. Officers said tips led them to Haywood's arrest.
St Louis County Prosecuting Attorney Robert McCulloch said during a press conference that Haywood saw the Dodge Charger car, which belonged to Owens, and waited for the owner to approach the vehicle.
He then walked up behind her, demanded she give him her keys and money and then shot her as she turned around.
As Owens lay on the pavement, police said Haywood tried to take the car but it wouldn't start. He grabbed her purse and phone and fled. Authorities said Haywood also took a gun Owens had been carrying in a holster at her hip.
Meanwhile, Owens' eight-year-old son hid his four-year-old sister and three-year-old brother under their car and flagged down help before returning to his mother's side, according to his great-grandmother, Fannie King.
Police said after Owens was shot she got up and walked to a neighbor's house but collapsed outside. She was pronounced dead at the hospital.
'The children witnessed this, and they watched their mother essentially bleed to death,' McCulloch said. 'You just want to cry when you think about it.'
Haywood is charged with second-degree murder, first-degree robbery and two counts of armed criminal action. Bail was set at $1million, cash-only.
