The investigation into the deaths linked to Rex Heuermann continues. Three cities are now re-investigating unsolved deaths in their area looking for connections to Heuerman. Other evidence found by investigators includes, computer searches showing disturbing titles of bondage, torture and  child pornography. The accused killer also drives a Chevy Avalanche described by a witness. He's caught on surveillance video buying more minutes for a burner phone. Investigators have determined a hair found on one of the victims is a DNA match to Heuermann's family.
