The horse ranch owner involved in a wreck that killed one child and injured five others has been indicted on additional charges.

Lynda Mescher had already been charged with one count of injury to a child, now she has been indicted on one count of manslaughter and one count of injury to a child with serious bodily injury, as well as four counts of injury to a child.

Prosecutors said Mescher had six children from the Silver Trails horse ranch in the bed of her pickup when it rolled over at the Grelle Recreation Center near Lake Travis.

Brianna Plehn, 11, died.

Mescher bonded out of jail after the original charge. The Llano County District Attorney's Office said it will not have her arrested again.
