Scott Kimball’s 10-year-old son is severely injured when a 200-pound metal grate falls on him while playing on Kimball’s rural Adams County property.

Rather than waiting for paramedics, Kimball rushes his son to Louisville’s Avista Adventist hospital, but the boy falls from the Jeep en route, Kimball tells doctors.

After two weeks in a coma, Kimball’s son recovers enough to tell his own story: He remembers his father telling him to turn around and dig a hole near the grate before it fell, then pushing him by the face from the speeding Jeep.

Because of the boy’s head injuries, though, doctors say he’ll be an unreliable witness.

Boulder County prosecutor Katharina Booth suspects Kimball tried to kill his son, but she’s unable to build a provable case.

Employees at the Lafayette insurance office of Scott’s mother tell investigators that Barb Kimball changed her grandson’s life-insurance policy as soon as she heard about the accident. Scott Kimball had been the sole beneficiary.

One employee says Barb Kimball suspected her son tried to kill his own child to cash in on the $60,000 policy.
