South Dakota Father Charged In Killing Of 8-Week-Old Infant

SIOUX FALLS, S.D. (AP) — A Sioux Falls father on Tuesday was charged in the killing of his 8-week-old infant who authorities determined died from an apparent assault.

Prosecutors charged Dylan Castimore with second-degree murder and first-degree manslaughter in the baby's death. Police Lt. Terrance Matia said Castimore has been arrested. It was not clear if he has an attorney who can speak on his behalf.

A coroner found the baby’s skull was fractured from an assault and he had a lacerated liver, according to court documents.

“The injuries were very extensive and it would shock most people,” Matia said at a news conference Tuesday.

Police officers responded Saturday to a 911 call from Castimore who said his infant was not breathing at his apartment in Sioux Falls, the Sioux Falls Argus Leader reported. After the child died at a hospital, police began investigating his death.

According to court documents, Castimore told authorities that he had been feeding his son with a bottle when the baby's eyes started to “gaze,” blood started to come from his nostril and he stopped breathing.

Castimore's Facebook page contained a tribute to his son, saying, “Your daddy will never ever forget the times we had I will never forget your dimples and your ocean blue eyes.”

However, according to court documents, a police detective testified that video footage from a security camera contained audio of a baby crying followed by the sound of slapping or hitting as well as loud thuds. Police also found smears that appeared to be blood in Castimore's apartment.
