Should I report a murder I witnessed 20 years ago if the killer is already in prison for another murder?
In 2004, when I was 14, I was dating a man who was 22. He was violent, abusive, and I genuinely believed he was capable of killing me. During that time, I witnessed him murder someone. I was terrified and never told anyone.
I moved away when I was 20 and tried to leave that part of my life behind. Years passed, and I convinced myself there was no point in coming forward. Then, in 2020, he was arrested and convicted of a different murder.
The part that haunts me is that he killed both victims in exactly the same way. After his conviction, his mother somehow tracked me down and reached out to me. Now I'm convinced that if I come forward, he'll know it was me. He only got 15 years for the second murder, and I keep wondering if I should tell the police what I know or stay silent and hope he never gets out.
ETA: I did not wish to give a ton of details but this is important. In 2020 he gave someone something that killed them. Texts proved it. It was not what the person thought they were getting. Then in 2004 I saw him give a kid, maybe 17, something and he died that night from it. I do not know what his parents know or think about it. Police never got involved and it was ruled an accidental overdose. To me this is murder. I did not feel it was back then but now I know that it is murder. However there is no evidence beyond something I saw 22 years ago.
