Sumter, SC (WLTX) - The State Highway Patrol is still investigating what caused a city of Sumter truck to crash into a home on Monday.

Three adults and a two-year-old were taken to hospitals in the area. The two-year-old and his father were sitting in their living room when the truck rammed into their home.

The family says they believe the two-year-old will be okay, after suffering a broken wrist and deep cuts. His father, who suffered road rash, returned home from Palmetto Heath Tuomey on Monday night, but was later sent to a Columbia hospital.

His family said in a brief phone call, that they believe his condition is worse than what they expected and they are focusing on his health.

It is unclear if the two Sumter employees, the driver and passenger, were released from the hospital.
