A man filed a federal lawsuit Monday alleging he was paralyzed and needed his legs amputated after police officers in St. Petersburg, Florida, put him in restraints, placed him in the back of a police van without a seatbelt and then drove in a reckless manner. Heriberto Alejandro Sanchez-Mayen filed the lawsuit in US District Court for the Middle District of Florida against the city of St. Petersburg and officers Sarah Gaddis and Michael Thacker. After being handcuffed, Sanchez-Mayen was placed in the back of [a police] van where there were no seatbelts. Thacker allegedly drove "in a reckless manner and at an unsafe rate of speed," before he suddenly came to a hard stop at an alleged red light, the suit states. The hard stop caused Sanchez-Mayen to be thrown forward, and his head struck a metal partition. After driving to the Pinellas County jail, Thacker opened the rear doors of the van and found Sanchez-Mayen "lying face down, motionless, unconscious, and unresponsive," the suit states. The officer unsuccessfully attempted to wake him up and then dragged his limp body out of the van, causing Sanchez-Mayen to hit his head on the bumper, the door and the concrete floor. Sanchez-Mayen suffered spinal cord injuries that left him a quadriplegic, or paralyzed in all of his limbs, and resulted in the amputation of both of his legs. The lawsuit states Sanchez-Mayen should not have been arrested in the first place, noting the criminal trespassing charge was later dismissed.
