Lockwood allegedly set up fake social media and email accounts as well as internet-based phone numbers to deliver the threatening messages, while concealing her identity.

Through an investigation, detectives said they found Lockwood and determined that although the threats were specific in nature, she had no means to carry them out.

It’s unclear at this time what connection Lockwood may have to the family and a motive for the crime has not been disclosed.
