Police investigating a husband’s alleged knife attack on his wife discovered that the had been having an ongoing affair with a teen student at the school where he was a math teacher.

WZZM 13 reports that James Philip Chelekis, 32, of Wyoming, Michigan, pleaded guilty to three felony charges, including assault with intent to murder.

Chelekis reportedly pleaded no contest to assault charges stemming from the June 2017 knife attack on his wife. He told investigators that he armed himself with a knife during an argument with his wife on June 27. He said his wife was cut with the knife when the two fell on the ground. Police reportedly found the victim with defensive wounds on her hands and slashes on her neck.

The couple’s children were home at the time of the attack but were unharmed. The suspect’s wife reportedly filed for divorce after the assault.

During the course of the investigation, police reportedly discovered that Chelekis, a former math teacher at Crestwood Middle School, had been having an ongoing relationship with a now-15-year-old student at the school. The teen reportedly told investigators that the relationship had continued for a year and a half.

Chelekis is no longer employed by the school district, and pled guilty to two counts of first-degree criminal sexual conduct. Police said there was no evidence that Chelekis’s wife knew about the sexual relationship with the student at the time of the assault.

The suspect entered his guilty pleas on January 2 as his trial was about to begin. If found guilty, Chelekis could be facing life in prison.
