(McKINNEY, Texas) — “Today I am proud to announce that the Grand Jury of Collin County has indicted Billy Chemirmir for four additional cases of capital murder,” said District Attorney Greg Willis.
“These indictments should serve as a reminder that every victim of a violent crime deserves to have their case investigated and prosecuted, and Collin County law enforcement and prosecutors will work every day to hold violent offenders accountable. I’d like to thank the Grand Jury for their diligent consideration of these cases, and I’d like to recognize the Frisco Police Department and the Plano Police Department for their investigative efforts that led to these indictments,” added Willis.
The cases encompassed in today’s indictments are victim Marilyn Bixler, age 90, murdered in Frisco on Sept. 17, 2017; victim Diane Delahunty, age 79, murdered in Plano on Dec. 3, 2017; victim Helen Lee, age 82, murdered in Frisco on Sept. 2, 2017; and victim Mamie Miya, age 93, murdered in Plano on Dec. 8, 2017.
Chemirmir has been previously indicted in Collin County in five cases of capital murder and two cases of attempted capital murder. These cases remain pending awaiting the October 2022 trial of Chemirmir in Dallas County. Accordingly, the Collin County District Attorney’s Office will have no further comment.
At the request of the families involved in today’s cases, the District Attorney’s Office is releasing their joint statement:
“We the families and loved ones of Marilyn Bixler, Diane Delahunty, Helen Lee, and Mamie Miya are grateful to hear of today’s four additional capital murder indictments. These indictments are another step in holding Billy Chemirmir accountable for the full extent of his horrible crimes. We’d like to thank police and prosecutors for listening to us, and for their continued efforts to see that justice is done for all the victims and their loved ones.”
