Newly released video shows the moments a Florida drawbridge opened while a car was still on it.

MIAMI – A bicyclist who ignored warning signs and tried to beat a Miami drawbridge slid to his death down the rising concrete slab, police said. Medina was an entertainment and technology executive who mostly worked in Latin American media. He was a principal of Redline Advisors, a media marketing consulting firm, and before that he was managing director for Latin America for BBC. He also previously held executive roles at Ole Communications, A+E Networks Latin America, and HBO Latin America, according to his LinkedIn profile. Medina often woke up at 4:45 a.m. to ride his bike, the Herald reported, and would post his rides on social media.
