When cps fails a child JUST to keep them with their mother

I always hated how states think moms automatically deserve full custody just because they pushed a baby out. Where we live it's hard for a father to get full custody. My boyfriend has a son who was 16 and wanted not go lobe with him because his mom is a useless junkie am her boyfriend is too.and her boyfriend beats him. My boyfriend and his son are very close and he has been fighting a custody battle for a few YEARS. Take one look and you know that bitch is unfit but because she's the "mom" she gets custody and gets to put him on child support. Her son was nothing to her besides a check. Monday was a very sad day. His mom was tripping off drugs and shot him.... He ended up in the hospital. My boyfriend wss a wreck in the hospital. He held his sons hand told him to be strong and he son would say very weak "Just let me go. He kept.saying no and crying and saying how much he loves him and his son would say I love you too. His son started flat lining and my boyfriend panicked and they called a cold blue and tried to bring him back and tried to get.my boyfriend to leave. He was yelling at them.. His son died at 3:37am... The scream my boyfriend let out was of pure agony.... RIP Philip James Mason...
