(Plano, TX) — Two women are under arrest in McLennan County on suspicion of being involved in the murder of a Plano couple.

Deputies arrested 29-year-old Cynthia White and 23-year-old Carmen Moreno on Sunday night on I-35 south of Waco.  They were driving two stolen cars and were found with meth and a bloody knife, along with IDs, cellphones and credit cards belonging to a couple in Plano.  The cars were registered to a Plano address, and when police did a welfare check, they found a man and woman in their 70’s who’d been stabbed to death.

White and Moreno are being held on numerous charges in McLennan County and now face double murder charges in the Plano case.  The victims’ names haven’t been released.
