2006 Toyota Corolla cruise control problems

My mother was driving a 2006 toyota corolla and was pulling into her parking place at her apartment (estimated moving only several MPH). When she took her foot off of the accelerator to brake, the car suddenly lurched forward accelerating very fast, jumped the curb, and crashed through the building wall and into a neighbor's apartment. The car struck the tenant inside, causing extensive injuries. The police surmised her foot hit the accelerator, but she kept repeating 'the car suddenly jumped forward on its own'.

Tl* the contact owns a 2006 toyota corolla. The contact attempted to yield for a vehicle ahead of him while depressing the brake pedal from speeds of 10 MPH. The vehicle abnormally accelerated and crashed into the preceding vehicle. The vehicle did this repeatedly until coming to a stop without driver interference. The manufacturer was contacted and stated that they would send an investigator to further evaluate the failure.
