After Byus returned home, he called Chandler and told him he had his wife's phone and discovered she had been texting another man and making fun of him. There were also pictures of the other man's genitals on her phone.
Chandler said Byus was very angry and threatened to kill Cathy Byus. He said he told Justin Byus not to do anything stupid and offered to let him stay at his house for the night. Justin Byus declined and said he would cool off.
Justin Byus called Chandler again about 3:30 a.m. and said he had killed his wife. Chandler did not believe him, but called 911 after calling Byus back and confirming that he was telling the truth.
The couple's 2-year-old son was home when his mother was killed and was taken into custody by the state Department of Human Services. He is in the care of relatives now, Adler said.
Pottawatomie County District Attorney Richard Smothermon said he expects to file murder charges against Byus next week. He is being held at the Pottawatomie County jail without bail.
