Three and a half years after suffering a heart attack the day after he was convicted of kidnapping a Newton business owner, Douglas Stangeland has awakened from his coma.

Stangeland's condition remains "very serious," and though he is conscious, he is unable to communicate, Sussex County First Assistant Prosecutor Gregory Mueller told the New Jersey Herald Wednesday.

Stangeland, 55, is being treated at the medical wing of South Woods Prison in Bridgeton.

After a six-week trial, Stangeland was convicted on May 7, 2015, of conspiracy to commit murder, first-degree kidnapping, robbery, attempted extortion and possession of a weapon for an unlawful purpose, among other charges. He fell into a coma the following day and remained in a vegetative state on life support before recently gaining consciousness.

He has not been formally sentenced.
