An autopsy determined that the boy—Samuel Dahlke—had succumbed to effects of a head injury suffered when he was about 6 weeks old.
Springfield was convicted in 2006 of abusing the boy in 2005 at an apartment in San Diego. Springfield, who was 23 at the time, was sentenced to four years probation, according to a spokeswoman for the District Attorney's Office.
The preliminary hearing is scheduled for 8:15 a.m., Friday, Feb. 28 in the San Diego County Courthouse.
