On Monday, a warrant was released stating that Cox confessed his guilt to his sister shortly after the crime.
The warrant states that after the murder, Cox fled to an apartment he shares with his mother, sister and another man.
According to the search warrant, Cox told his sister he stabbed his manager, Danielle Watson, several times during an argument and then dumped the pregnant woman’s body in a dumpster in the shopping center.
Cox told his sister he had planned to dump the clothes and Watson’s stolen car in a river, according to the warrant.
Cox’s sister showed police where her brother’s bloody work-clothes were stashed; in a white plastic bag in her closet, when they arrived a day later.
Moments after visiting his sister, Cox visited another Flying Biscuit employee, who told police Cox was holding a handful of money and driving a two-door car that he identified as Watson’s. investigators determined.
When detectives went to Cox’s home, they found a trail of blood leading from the parking lot to the front door of his apartment. Once inside, they found more blood throughout the apartment and a bloody butcher knife sitting in a mug.
Cox was charged with Watson’s murder as well as the murder of her unborn child. This is the first time prosecutors will be able to use the Unborn Victims of Violence Act since it took effect in December.
