SAN BERNARDINO, Calif.– A 40-year-old Long Beach man was sentenced to state prison today for the murder of his girlfriend’s 9-month-old baby in December 2007.

Victorville Superior Court Judge Eric M. Nakata sentenced Arthur Lee Holmes to 40 years to life in state prison for the murder of 9-month-old William Lacey (pictured above).

Last month, a jury found Holmes guilty of one count of second degree Murder and one count of Assault on a Child Causing Death after four days of deliberations.

According to Deputy District Attorney Kathy DiDonato, who prosecuted the case, the child died from blunt force head trauma with a skull fracture, bleeding of the brain and retinal hemorrhages.

“The pathologist testified that the injuries to the victim were consistent with injuries seen during car crashes where the victim is not in a safety seat properly,” DiDonato said. “These types of injuries are consistent with shaken baby impact.”

Prior to the sentencing William’s grandfather, Charles Hill, read the following Victim Impact Statement (excerpted):

“…He was such a good baby. He was just starting to walk around the coffee table, laughing and having a good time. William and his sister would have such a good time playing peek-a-boo. I guess that’s gone now that he was taken away from us.”

This case was investigated by the San Bernardino County Sheriff’s Department.
