A West Jordan man is in jail after allegedly shooting his son in the shoulder during a family Christmas party.

The 44-year-old man and his 24-year-old son started fighting when the son confronted his father about calling his grandmother a name Friday night, according to a probable cause affidavit by the West Valley Police Department.

The man punched a woman in the home, at which point the son hit his father and wrestled him to the ground, the document states. The son let his father back up after he thought the father had calmed, according to the affidavit, but the father went into his bedroom and came out with a gun and shot his son in the right shoulder.

Several other shots were fired as the son wrestled the gun away from his father, documents state.

The son was taken to a hospital and was expected to survive.

According to a portable breath test, the alleged shooter had a blood-alcohol level of .142, documents state. He was booked into the Salt Lake County jail on suspicion of multiple charges, including aggravated assault.
