Yeah, these articles are always written so poorly.
From what I can gather she went to the prison to visit, he walked out with her and slapeed her around a bit and forced her to drive him to Lakewood.
She then called the cops to tell them what happened. Somehow they then all ended up at the family’s former home, where he killed them.
This article, based on the teenage survivor’s statements, is quite a bit clearer. I’m still not clear on the actual departure from the prison. Did he convince her that he was allowed to leave for a while, so that she actually didn’t know she was “helping him escape”? Obviously, this prison is run as a no-security prison, not a minimun security prison, if prisoners are just having relatives come pick them up and drive them away.
