DELAWARE COUNTY, Ind. - The SUV involved in a fatal rollover crash at more than 110 mph was recently in the shop with a throttle problem, a source told RTV6.
A family member of Lisa Case, 47, who was driving the SUV Sunday when it crashed, told RTV6 Case was an overly cautious driver.
"She loved kids. She would not hurt those kids for any reason," said Case's sister, Betty Lloyd. "If they were egging her on to speed, she wouldn’t have done that. She has a daughter, she has a grandchild of her own. She just wouldn’t do that."
The crash killed Case, her boyfriend Kent Kalley, 47, and Andrew Lackey, 12.
Investigators said the SUV was traveling faster than 110 mph when it crashed, killing three and injuring three others.
Delaware County officials said the 2006 Cadillac SRX also ran a stop sign prior to the crash.
Savanna Kalley, 13, Trace Joiner, 13, and Jessica DeLong, 12, were all hospitalized with injuries related to the crash.
Tuesday, Joiner and DeLong were both listed in good condition, but Savanna Kalley was still in critical condition, officials said.
Investigators are planning to interview Joiner, and they hope he can shed light on the events leading up to the crash.
Investigators have ruled out medical causes for the excessive speed. They've also ruled out mechanical causes, but Case's family thinks something must have gone wrong.
"She would have never done any of this on purpose," said Case's daughter, Lindsay Simanek. "It's just a freak accident."
