Yesterday after 2 hours of deliberation, John Lee Cowell was convicted of first-degree murder for the stabbing death of 18-year-old Nia Wilson at MacArthur BART station in Oakland in 2018.
Cowell was also convicted of premeditated attempted murder for stabbing Wilson’s sister Letifah Wilson, who survived the attack.
Cowell could face life in prison without the possibility of parole. He has a history of mental illness and on Wednesday the sanity phase of the trial will begin, with the same jurors to decide if he was legally sane during the attacks.
The Wilson family is happy with the verdict. After leaving court Letifah told, NBC Bay Area news,
