A Kentucky man charged in his 4-month-old son's beating death has been found competent to stand trial.

The News-Enterprise reports (http://bit.ly/1OPoK3w ) 35-year-old Daniel Antoine Cox was determined mentally able to stand trial following an evaluation by doctors.

Cox is charged with murder-domestic violence in the death of Jayceon Chrystie.

Court records say witnesses called 911 on Aug. 6 after seeing a man driving down a highway beating an infant in a car seat. Cox left the unresponsive infant with the baby's mother, who called police. Authorities say the child was black and blue, had no pulse and his eye was swollen shut.

Jayceon died two days later at a hospital. Jefferson County Deputy Coroner Bob Fraction said the cause of death was "inflicted traumatic injury to the head."
