Ralkina Jones was found dead in her jail cell in Cleveland Heights City Jail on Sunday morning.

Cleveland Heights police accused the 37-year-old of striking her ex-husband in the arm with a tire iron outside of a Save-A-Lot food store. She then hopped into her automobile and allegedly came a few feet away from running over her ex and his friend — with her 11-year-old daughter in the backseat.

Police then arrested Ms Jones, however, her ex-spouse decided not to press charges against her.

The Cuyahoga County Medical Examiner performed a preliminary autopsy on Monday and said the woman had suffered no suspicious injuries but a full report is pending. In a statement, officials said that the woman was observed by medical professionals three times from Saturday evening into Sunday morning.

At 7:15pm, officers noticed that Ms Jones appeared sluggish and phoned the Cleveland Heights Fire Department. At 10:40pm, she was released back to the jail after an evaluation at HealthSpan hospital.

At 12:45am, on Sunday, she was checked and her vitals which appeared normal. At 7:30am, she was found unresponsive on her bed.

Renee Ashford, the woman's sister, told Cleveland.com on Monday that her sister was fine when they spoke on Saturday: "She was perfectly fine. She didn't complain of nothing, saying she was hurting or anything.”

She said the family has begged the department for more information to no avail: "Every time we call we don't get an answer and that's the upsetting part.”

"One thing I could say about my sister is she would want us to find out why? You can't just tell me one minute I see my sister and the next day, she dead."
