Kenneth Charles-Alan Stringfellow, 25, of Quincy, could face life in prison for the murder of 22-month-old Braylon Duguay.
After one day of deliberations, a Plumas County jury late Thursday found Stringfellow guilty of second-degree murder and felony assault in the death of a child.
The jury of three women and nine men acquitted him of domestic violence against Demi Nicole Sullivan, 21, Braylon’s mother.
On Dec. 11, 2013, Sullivan left her son alone with Stringfellow, her boyfriend, for around nine hours. Stringfellow admitted that during the day he bit and “spanked the crap” out of the toddler to discipline him.
Plumas County District Attorney David Hollister argued that Stringfellow repeatedly pummeled the child, resulting in bruises, bite marks and the concussive blow that caused his death after “a long and horrific day.”
Braylon died Dec. 13, 2013, in a Reno hospital.
Hollister said Friday he was pleased with the verdict after what he called “a grueling trial.” In addition to the “awful subject matter,” tension was heightened because both the victim and the defendant were from Quincy and their families attended most of the proceedings, Hollister said.
Defense attorney Craig Leri said he plans to appeal. The issue was whether Braylon’s injuries were cumulative or caused by one catastrophic blow.
“The jury concluded they were cumulative,” he said.
Leri directed blame for Braylon’s death toward Sullivan, who spent between 10 and 15 minutes alone with her son while Stringfellow stepped out of the Quincy apartment they shared.
Stringfellow showed little reaction to the verdict, remaining unemotional as he had throughout the trial that began March 9. He faces 15 years to life in prison for second-degree murder, and 25 years to life for the assault that caused Braylon’s death.
Plumas Superior Court Judge Ira Kaufman scheduled Stringfellow’s sentencing for 11 a.m. June 12.
