(AP)-- A Philadelphia man is on trial on charges that he put heroin and methadone in a bottle to quiet his infant son but instead killed him.
A friend testified Tuesday that he took 45-year-old defendant Orlando Rosado to a methadone clinic every day but says Rosado was still using heroin.
The friend, Giovanni Nieves, says Rosado was good with the baby and was "hysterical" the May 2012 morning that he ran outside carrying his limp, discolored son.
The boy, Christopher, died two days before his first birthday.
Nieves says the baby's mother was also in treatment and received take-home methadone, while Rosado took his methadone at the clinic.
Rosado is charged with third-degree murder and drug delivery causing death. He has told police he accidentally put the drugs in the bottle during a 3 a.m. feeding.
