OMAHA, Neb. (AP) — An Omaha dad has been charged with abusing his 3-month-old son who he claims was choking when injuries were sustained.

The Douglas County Attorney’s Office says the infant was diagnosed in April with subdural hematoma, or blood on the brain usually caused by severe head injuries.

A police report says the diagnosis came after 31-year-old Brian Swanson told officers the boy began to choke and he tried to help him breathe by hitting him on the back and sticking a finger in his mouth. The baby was rushed to a nearby hospital and later transferred to Children’s Hospital and Medical Center.

Swanson was charged Friday with felony child abuse and released from jail Monday. If convicted, he faces up to 50 years in prison.
