Kaiden Blane Chamberlain, a 5-month-old White male, was spending the day at a southwest Las Vegas home while his mother was at work when everything went wrong. In the days before, his family had sought medical help because the top of his head appeared to bulge; a scan showed no trauma and he was sent home. On Thursday, Aug. 29, 2013, the babysitter—Anthony Casey, a 31-year-old family acquaintance who had previously dated Kaiden's mother and was then a roommate—messaged her to come back
because the infant was “acting weird,” saying he might have bruised the baby's face when the child went limp. Paramedics took Kaiden to Sunrise Hospital and Medical Center. Two days later, on Saturday, Aug. 31, 2013, he died. Doctors determined he had suffered abusive head trauma consistent with shaken baby syndrome.
Police records described a grim scene and timeline. Casey told officers the child had been left in a swing for about nine hours that day, taken out only for diaper changes, and he offered no explanation for Kaiden's injuries, which included bruising, puncture marks, a bulging area on his head, and evidence of older rib fractures. When detectives tried to contact Casey at the residence on Souvenir Lane, near Lindell Road and Hacienda Avenue, he refused to come to the door and asked the mother to give police a false name for him. SWAT officers ultimately executed a search warrant; after flash-bangs were deployed, Casey surrendered.
The legal response moved quickly. Casey had been arrested on Aug. 29 on child-abuse charges tied to the injuries found while Kaiden was in his care; after the infant's death on Aug. 31, those allegations escalated, and he faced a murder charge. Public obituaries confirmed the date of death and attributed it to injuries from shaken baby syndrome.
