Cops couldn’t confirm or deny if Yasmine Elder’s boyfriend was cheating, but just the possibility had her caused her to do this to him.
Yasmine Elder, 24, was sitting in a van with partner Darrius Ellis, in Chicago when they got into an argument about cheating.
Prosecutors say Elder was able to overpower Mr Ellis, 26, and then pour bleach down his throat.
Police later found him unconscious on the ground near the vehicle in the early hours of Monday.
He was taken to hospital and pronounced dead at 3.26am, the Chicago Tribune reports.
What a horrible way to die, she needs to get life in prison without the possibility of parole.
She has been charged with murder, no bond has been set.
