(King City, OR)  --  A man who deputies say displayed rage over a child-custody issue is now in custody.  Bail is set at 50-thousand-dollars for Louis Jarvis Jr., who deputies say forced his way into the children's mother's King City apartment early Friday morning.  Authorities say the woman, who had armed herself, fired a gun at Jarvis and caused him to flee.  A warrant was issued for Jarvis' arrest before he turned himself in.
