ROBERT - Louisiana State Police report a bicyclist was killed Monday night when she was rear-ended by an SUV as she attempted to ride across the US 190 Tangipahoa River Bridge. 

The yet to be identified woman was pronounced dead at the scene by the Tangipahoa Parish Coroner's Office at around 10:30 p.m. State Police said the woman was riding her bicycle westbound on the bridge when she was hit from behind by a Ford Escape driven by 24-year-old Kateria Edmon, of Hammond.

Investigators said the woman was wearing dark colored clothing, and her bicycle was not equipped with headlamps or rear-facing reflectors. According to troopers, she sustained severe injuries during the collision and was thrown from her bike.

State police do not suspect Edmon was impaired at the time of the crash, but blood samples were taken from both Edmon and the deceased bicyclist to be sent to the LSP Crime Lab for toxicology analysis.

Troopers are currently working to identify the female bicyclist. Investigators describe her as a white woman in her middle to late 20's with long brown hair and brown eyes. She has a red Egyptian ankh tattoo on her left ankle.

Anyone who is able to identify the woman is urged to contact Louisiana State Police Troop L at (985) 893-6235.
