One very important scene in 'When They See Us' was the moment when Korey Wise decide to leave his girlfriend and join Yusef Salaam in Central Park.
Like many of, one person Twitter was left wondering what happened to Korey's girlfriend since she was never shown again during the court of the series. So he tweeted Ava saying "im still stuck on what happened to koreys girlfriend did they reconnect after he was released" and Ava responded explaining that she was passed away.
"I’m sorry. Korey never reconnected with his girlfriend from the time of his arrest. Sadly, she passed away before he was released from prison 13 years later. Whenever Korey mentions Lisa to this day, he always adds “Rest in Peace.” I truly hope she is. #WhenTheySeeUs"
