Police have arrested a 25-year-old Maryland man after the bodies of three young children were found in a suburban home on Friday. Prince George’s County Police Department issued a statement naming the suspect as Antonio Williams, who is accused in the stabbing deaths of his 6-year-old sister and two other girls, aged 6 and 9. No details have been provided on a motive in the crime, which police described as “one of the most difficult scenes” they’ve ever encountered. Investigators say Williams was meant to be taking care of the three children when the crime occurred. An adult family member found the bodies of the children on Friday morning. All three suffered “trauma to their bodies,” though no further details were provided on their cause of death.
