The suspect, Carl Brandt, is no longer alive. Brandt hanged himself in 2004 after killing his wife and niece.
Investigators first linked him to the death of Darlene Toler after his suicide. Brandt's niece, Michelle Jones, was mutilated as was Toler -- her head was cut off and her heart removed.
Toler, last seen alive in Miami's Little Havana, was found in southwest of the city, her body shrouded in a blanket. Now, dog hairs from the blanket are being compared to hairs found in Brandt's pickup truck.
Brandt and his wife, Teri, lived in the Florida Keys. He and his wife were staying with Jones in Seminole County north of Orlando to shelter from Hurricane Ivan when he killed the women and himself.
Rob Hemmert, a Seminole County homicide detective, said he has received telephone calls from police departments around Florida and the country with unsolved cases.
