The teenage stepdaughter of Howard Gregg Diamond, the Sherman pain doctor charged in the deaths of seven patients who overdosed on medications he prescribed, was found dead in a Dallas creek Sunday.

The Dallas Morning News reports that 17-year-old Mikayla M. Mitchell’s body was found floating in a creek in the 3000 block of Rochester Street shortly before noon. The Dallas Medical Examiner confirmed the girl’s identity on Tuesday and the Dallas Police Department attributed the girl’s death to homicidal violence.

Mitchell was the daughter of Jennifer Diamond, who is married to Howard Gregg Diamond.

A representative from the Dallas Police Department did not answer questions submitted by the Herald Democrat in an email and said all available information into the case could be found on the department’s blog.

Howard Gregg Diamond’s lawyer Peter Schulte took to Twitter Tuesday afternoon and said there was no connection between the criminal case against Diamond and his stepdaughter’s death.

Media is ruthless. There is no connection between my client Dr. Diamonds' charges & his step-daughters death. Client & family devastated

— Lawyer Peter Schulte (@AttyPeteSchulte) July 18, 2017 A search of Mitchell’s Facebook profile listed her most recent place of residence as Denison and says she had previously attended Sherman High School.

Sherman Independent School District officials said Mitchell had been enrolled in SISD since kindergarten. She was enrolled in the Juvenile Justice Alternative Education Program and the Grayson County Juvenile Detention Center Boot Camp, both alternative education programs served by the SISD. Mitchell withdrew from SISD in 2016.
