DALLAS - A Dallas man has been charged with killing his mother whose body was found after an argument heard by one of her friends via cellphone.
Dallas County jail records show 25-year-old Gonzalo Lopez was being held Monday on a murder charge.
Jail records don't list an attorney for Lopez, whose bond was set at $750,000. Police say Lopez allegedly used a wrestling hold to strangle his mother.
Dallas police on Saturday night found the body 51-year-old Isabel Kristina Lopez in her home. A friend of the victim called police after hearing a fight in the background during a call from the woman.
An affidavit says the son told police that he and his mother argued and he thought he killed her. Police are trying to determine what prompted the dispute.
