A Virginia grand jury has indicted the father of missing 4-year-old Codi Bigsby on charges of murder and tampering with a body.

Cory Bigsby, 43, previously told police that he last saw his son at a Norfolk apartment complex in February 2022 around 2 a.m., but former Hampton Police Department Chief Mark Talbot said during a press conference at the time that the information Bigsby provided was "not reliable."

Bigsby's attorney, Amina Matheny-Willard, maintains his innocence.

"We maintain Cory Bigsby’s innocence and we are deeply, deeply disturbed by the unconstitutional and coercive actions taken by the Commonwealth through its agents at the Hampton Roads Regional Jail," Matheny-Willard said in a statement to 13NEWSNOW.
