(KCEN) -- The body of Jessica Ridgeway was found in a park in suburban Denver and now police have some ideas of what her killer might be like.
Ridgeway disappeared a week ago as she was walking to school.
Investigators say the person behind the crime may display abnormal behavior.
Such as missing work or appointments, reacting strongly to news coverage of the crime, or changing his physical appearance.
FBI Spokesman Dave Joly says, "It could be something as simple as shaving of the face. It could be changing of hair color, cutting of their hair."
Officers continue to search where the body was found.
Ridgeway's body was not intact and parts of the body were missing.
Profilers say the murderer is most likely a man and possibly a local.
