The witness admitted changing his story to make the defendant look bad.
Also, that witness took a video of what happened. Supposedly part of the video was lost transferring it to the detective. That witness then dropped his self phone in the water and couldn’t recover the video. The defense implied the missing part was the early part showing what the kids were doing.
I don’t understand how they got a grand jury and a magistrate to agree to murder 1 charges. Maybe they were pressuring him to plead guilty, but I doubt they offered a plea to manslaughter. I could see charging him with voluntary manslaughter or whatever serious kind there was in that state.
They have been able to discredit every single witness. The defendant should sue all of them. The video speaks or itself.
