Dannie Joe Farnum, 30, of Anza was found guilty of second degree murder. Farnum was arrested and accused of killing the infant son of his girlfriend, Delice Sharon Preston, in November 2008.

Farnum was watching the infant while Preston went shopping. During this time, he apparently dropped or beat the child. When Preston returned, Farnum went to the infant’s crib and cried out that he was not breathing. They called for emergency help. The baby died at the hospital.

Farnum could never explain to investigators how the infant was injured and the fact his own 6-year-old daughter, who was 4 years old when the incident happened, was videotaped discussing how her father had shaken the infant.

The jury took less than 24 hours to reach the guilty verdict. Farnum’s sentencing is scheduled for Oct. 28.
