TAMPA, Fla. (WFLA) — Two people were killed in a seven-vehicle crash in Manatee County, according to the Florida Highway Patrol.

The woman and child did not survive.

Three other people were injured in the crash. According to the FHP, the driver in the first vehicle, a 25-year-old Sarasota man, suffered serious injuries.
