The criminal case against a Utah man accused of fatally shooting his brother is on hold after an 8th District Court judge found him incompetent to stand trial.

Craig A. Antonio, 27, is charged with first-degree felony murder in connection with the April shooting death of 23-year-old Tyson Macartin Antonio.

If convicted as charged, Craig Antonio could face a penalty of up to life in prison.

On Tuesday, Judge Clark McClellan ruled the defendant was not competent to stand trial, meaning experts don't believe Craig Antonio understands the charge filed against him and can't participate in providing his own defense.

McClellan ordered the defendant be treated at the Utah State Hospital in an effort to restore competency, according to court records. No future court dates had been set as of Wednesday.

Tyson Antonio was found dead by his mother at her Ballard home, near 1400 South and 1500 East, on April 11. A medical examiner later determined that the man had been shot in the head, and deemed the death a homicide.

In a police interview conducted the same day his brother's body was found, Craig Antonio allegedly admitted that he had argued with his brother and shot him in the head, according to the charges.
