Former NFL Player Sergio Brown pleaded not guilty Wednesday to charges of first-degree murder and concealing a homicide in the September death of his mother.

A prosecutor says former NFL player Sergio Brown bought a one-way ticket to Cancun, Mexico, after being the last person seen with his mother before her slaying last month.

Authorities say former NFL player Sergio Brown has been arrested in Southern California nearly a month after the body of his 73-year-old mother was found behind her suburban Chicago home.

Police in suburban Chicago are checking on the authenticity of Instagram videos that appear to show missing former NFL player Sergio Brown discussing the recent death of his mother.
