HARRISONVILLE, Mo. -- Detectives investigating the killing of a 30-year-old woman in her Harrisonville home found a pickup truck they were looking for and determined that neither the driver nor the vehicle were involved in the homicide, they said.

Cara Jo Roberts' husband discovered her body in their home in the 800 block of North Patton Street on Wednesday, investigators said.

Investigators said there were no signs of forced entry into their home, and her family said they had no idea who would want to kill the woman they described as a loving mother of a 2-year-old boy.
