Former NFL player Sergio Brown appears to resurface in a rambling video as police investigate his mother’s death as a murder

Former NFL player Sergio Brown appeared to resurface on social media Monday, days after he was reported missing following the death of his mother, whose body was found in a creek near their Illinois home.
Brown appeared to post a video to an Instagram account called @intplayerwithapassport, even though he already has a verified account on the platform. The former defensive back shared a rambling message while apparently at a vacation resort talking to his followers.
“Fake news. Fake news. Fake news,” Brown said in the video tagging ESPN. “It must be the FBI that came to my house with 511 and unwarranted gas on the day Bob Marley died. They kidnapped me from my home twice – the Maywood Police Department. It had to be the FBI or the Maywood police.”
