A 21-year-old Utah man has been arrested on suspicion of being drunk when a boat he was driving smashed into a rock at Lake Powell, causing a woman to be thrown from the boat and die.

A probable cause statement says Triston Brady Harrison was arrested Friday after the fatal accident when he showed multiple signs of being intoxicated.

The victim wasn't identified in court documents.

Harrison is arrested on suspicion of three charges related to the incident, including DUI and automobile homicide.

He is jailed in Kane County, Utah. It's unknown if he has an attorney. He had not yet been charged as of Monday.

Court documents show Harrison has previously pleaded guilty to criminal trespassing and drug and weapons charges.
