According to our news partners at WPXI-TV, Pennsylvania State Police are searching for a man charged in the death of his new girlfriend’s infant daughter Saturday night at an apartment complex in East Huntingdon Township. Derrick Bass, 29, is charged with homicide after the 11-month-old girl was found dead in a Pack ‘n Play at the Laurel Hill Apartments on Gurley Drive, investigators said. The baby’s mother told police Bass was supposed to be watching her daughter and his two children. He was also supposed to pick her up from work, but never showed up. When the girl’s mother got home, she noticed her daughter and various electronic items were missing, according to a complaint. She called police shortly after 11 p.m. Police responded to the apartment shortly after 12:30 a.m. after the mother reported finding her daughter unresponsive in the Pack ‘n Play, the complaint said. She did not see her until that time because the baby was covered in blankets. An autopsy was conducted Sunday morning, and the preliminary cause of death was determined to be drowning, authorities said. Bass, also known as Hector, is described as being 5 feet, 11 inches tall and weighing 300 pounds. He might have reddish hair. Police said Bass might be traveling with two juveniles. Anyone with information on Bass’ whereabouts is asked to call 911.
