A Germantown, Maryland, man who shook his crying 5-month-old son to death will spend 30 years in prison.
Austin Ahimbisibwe was sentenced Monday for the death of Hudson Ahimbisibwe.
"A day does not go by that I don't think about him," he said in court. "It's my fault. I want to apologize to my baby. Daddy is sorry for my lack of composure."
Ahimbisibwe called 911 June 23, 2016, and said he was performing CPR on his son because the baby wasn't breathing, Montgomery County Police said.
Hudson was taken to Children's National Medical Center in Washington, D.C., where he was pronounced dead.
Hudson's mother, Lauren Felitti, left him in Ahimbisibwe's care while she was at work, police said. She told investigators Hudson was in good health when she left him with Ahimbisibwe.
Felitti said Ahimbisibwe lied about what happened to Hudson for four months until the autopsy results came in.
A medical examiner ruled his death a homicide caused by head, neck and upper body trauma, police said.
Ahimbisibwe later admitted he became frustrated when Hudson would not stop crying, police said.
"Rather than call someone to try to help him when his child began to cry, he chose to physically abuse that child with a constellation of injuries," Montgomery County State's Attorney John McCarthy said.
Ahimbisibwe told detectives he grabbed Hudson by the neck and face, covered the baby's mouth with his hand and shook him to stop him from crying.
"If it were up to me, obviously he would sit in (prison) for life," Felitti said.
Before Ahimbisibwe was sentenced, supporters, including two of his former teachers from Seneca Valley High School, told the judge he is an intelligent, kind and caring person.
Ahimbisibwe was charged with second-degree murder and first-degree child abuse resulting in death.
