Faulty tire likely cause of Florida crash that killed 6

Authorities say a separated tire likely caused a woman to lose control of her minivan, which crashed on a South Florida highway, killing four of her children and two other adults.

The Florida Highway Patrol says the driver and her 11-year-old daughter are in serious condition after the Saturday night crash.

Sgt. Mark Wysocky says in a news release that 33-year-old Heidi Solis-Perez's 2001 Mercury Villager veered into a concrete barrier and then bounced into the path of an SUV.

Wysocky says investigators are trying to determine how many passengers were ejected. Three people died at the scene, and three died at hospitals.

The dead included Solis-Perez's two sons and two of her daughters, ages 17, 14, 7 and 5. Her 31-year-old boyfriend and an 18-year-old man also died.
