Son calls 911, admits to killing mother

A 24-year-old son calls 911 stating, "He had killed his mother."

When officers arrived to the home near 61st and Martin Luther King Jr. Boulevard around 8:45 p.m. Saturday night, they found the son walking out the door.

Police say a few moments later, they found his mother stabbed to death inside the residence.

It's believed Arthur Devaughn and Glenda Castaneda got into an argument, and the son pulled a knife.  Police say there was evidence of a struggle inside the home.

When officers found Devaughn outside the home, he had blood on his clothes.

He's currently in the Tulsa County Jail on a murder complaint.
