The mother of a man linked to an attack on Dallas police headquarters says that her son had a history of mental health problems but that she had no inclination he would become violent.
Jeannine Hammond told TV station KDFW Sunday she "never dreamed" her son James Boulware would attack police.
Police have said the suspect, who planted pipe bombs outside the headquarters and fired at officers early Saturday from an armored van, told them he was James Boulware, but a medical examiner hasn't officially confirmed the suspect's identity.
Hammond told the TV station she was awarded custody of Boulware's young son on Monday.
She described him as "an excellent father" for a time, until his mental health worsened.
James Boulware's father and brother have also said the man showed signs of mental instability.

Fourteen police officers who "engaged" with the gunman who opened fire at Dallas police headquarters have been placed on administrative leave pending an investigation.
Police said Sunday that the officers will be interviewed and offered counseling after the shooting early Saturday, in which a gunman rammed a police car with an armored van and opened fire in front of the police department.
No one was injured. A police sniper killed the gunman later during a standoff.
Police preliminarily identified the gunman as James Boulware, though the medical examiner has yet to confirm Boulware's identity.

Two years before he was linked to a violent attack on Dallas police headquarters, James Boulware was arrested after his family reported he was armed and might attack schools and churches in an East Texas town.
Boulware's brother, Andrew, told The Associated Press on Sunday that James Boulware talked about attacking "soft targets" in Paris, Texas, in a March 2013 incident. He was arrested on allegations that he choked his mother that same day, according to family members and police records.
Andrew Boulware said he had tried to get his brother help after that arrest, but was unsuccessful. He said his brother showed signs of mental instability, including telling people he had dreamed about events like the Sandy Hook Elementary School shooting in Connecticut before it happened.

The suspected gunman in an attack on the Dallas police headquarters had a record of behaving violently and making erratic statements.
A police sniper fatally shot the gunman, who authorities preliminarily identified Saturday as James Lance Boulware. Boulware was accused two years ago of choking his mother and attacking someone who tried to pull him off of her.
According to an arrest warrant affidavit, Boulware was "talking rudely about religions, Jews and Christians" toward his mother, Jeannine Hammond, before suddenly attacking her.
Three cases were eventually dismissed.
Jeannine Hammond said in a statement to local media that "we lost him to mental health long before we lost him to death." Boulware's father, Jim, said Saturday that he never thought his son would become violent despite a history of "making statements."
