I met Cowell when he was sentenced to prison for that second degree robbery charge. I would have never suspected him to be the murderer type, just the thieving type. Such a tragedy, never would have thought that would happen to Nia Wilson.

“Cowell, a transient based in Concord, has a history of arrests, including for assault with a deadly weapon and robbery. In 2016, a Richmond hospital sought a restraining order against him for allegedly calling a worker a “crack-headed (expletive)” and constantly threatening to kill her. He also had prior arrests in Alameda County for cases involving petty theft, misdemeanor vandalism and misdemeanor possession of a controlled substance.” https://www.eastbaytimes.com/2018/07/22/macarthur-bart-station-closed-for-police-activity/

In May 2016, Cowell was convicted of felony second-degree robbery charges, according to court records. He was previously convicted of battery in June 2013 and under the influence of a controlled substance in March 2016 — both of the latter incidents occurred in Walnut Creek. https://www.sfchronicle.com/crime/article/Manhunt-continues-for-suspected-killer-in-Oakland-13097698.php

John Cowell has a previous record and has had interactions with BART Police before, according to a statement from BART. It’s unclear exactly what his previous record is, but BART police said in a press conference that he was a violent felon currently on parole. A search of court records did reveal a John Lee Cowell with 2016 bookings in Alameda County for misdemeanor infractions of possession of a controlled substance, petty theft, and vandalism (malicious destruction of property.) We will add the felony infractions as soon as they are known. https://heavy.com/news/2018/07/john-cowell/

How horrible and tragic. Likely we will find that BART cameras were not working so there will be no pictures of the murderer, and in the event that they are caught that they are a repeat offender. Rest In Peace Nia Wilson. BART has completely failed you. https://www.sfgate.com/crime/article/BART-closes-MacArthur-Station-in-Oakland-after-2-13096466.php
