A man accused of murdering his infant son has entered a plea to a reduced charge of manslaughter and could face up to 15 years in prison when he is sentenced Feb. 15.

Jeremy Keith Wilson, 21, St. George, entered a so-called Alford plea, which is treated as a guilty plea although the defendant does not admit guilt, 5th District Court officials said Friday.In exchange for the plea agreement Thursday, prosecutors dismissed a second-degree murder charge against Wilson in the Aug. 20, 1987, death of his 2-month-old son, Landon Keith Wilson.

The boy was hospitalized after the father called paramedics and said the infant had stopped breathing. He died the following day.

The state medical examiner's office determined the death was caused by massive head injuries.

Defense attorney Clayton Huntsman said his client remembered nothing of the circumstances leading to the child's death.
