The child was rushed to Loma Linda Medical Center for treatment.  Both of the boy’s ears are severed, and he has numerous puncture wounds to his head and face, police said.

“The entire community is supportive and praying for a speedy recovery,” Fontana Police Department spokeswoman Martha Guzman-Hurtado said.  “Our hearts go out to this child and his family during this traumatic time.”
