DALLAS, Aug. 23 (UPI) -- A Dallas man held in the kidnapping and drowning of his two young sons successfully completed a substance abuse program recently, police said.
The program declared Naim Rasool Muhammad, 32, "ready to make the behavioral changes needed to become a pro-social and productive member of society," The Dallas Morning News reported.
Police questioned Muhammad late Monday about the deaths of his sons Naim, 5, and Elijah, 3, who were abducted earlier in the day while walking to school with their mother and a third sibling.
Police said that hours after Muhammad drove off with the two boys they received a call from a woman who said her grandchildren had been drowned.
Naim and Elijah were pronounced dead at Children's Medical Center in Dallas.
Police Chief Craig Miller said Muhammad had tried to abduct the couple's third child but was stopped by a relative.
"We're very fortunate that he didn't get his youngest child in this case and do harm to that child as well," Miller said.
Police and court records indicate Muhammad was prone to violence against his family.
