Fort Worth police are still asking questions about how a two-year-old boy was run over and killed last night. Joshua Ramirez was rushed to Cook Children's Hospital but it was too late to save his life. Police spoke with a neighbor who said she was backing out of the driveway when she felt her SUV run over something. She got out to check it out -- and Joshua's father quickly jumped in the SUV to roll it off his son. The two families share a driveway at their duplex. Even though it looks like a tragic accident, detectives have not finished their investigation -- so they're not saying whether the driver will be charged.
