When Lana Farren is about to leave the hospital, she has a severe bruise under her right eye. When she arrives at the Tibbs house a short time later, the bruise is almost completely gone.
An abandoned house, open to the elements, and not one speck of dust? Get real.
Antagonists Delissa and Smet park the Cadillac at a significant angle in the parking space in front of Lana Farren's motel room. But some time later when she arrives, the Cadillac is parked properly.
