A Warren man accused of fathering a child with his teen daughter changed his plea to no contest.

Gregory St. Andre, 37, pleaded guilty to four counts of criminal sexual conduct including one count of incest. His daughter, who was 14 at the time, is now 20 years old. 

St. Andre pleaded guilty to three counts of first degree criminal sexual conduct and one count of third degree criminal sexual conduct in a pretrial hearing a week ago. He originally had pleaded no contest, but in November withdrew his plea to go to trial. 

St. Andre will be sentenced on Feb. 4.


According to Warren police, the mother of the daughter came forward to police after the daughter gave birth to a boy. Police believe he began having sex with his daughter when she was only 14.

St. Andre told police he never had intercourse with his daughter. He told them he gave her a cup of his semen and he "doesn't know what she did with it."

However, Michelle Truszkowski, the aunt of the victim, says St. Andre called his daughter his wife.

"'You know I am the only one that will love you," Truszkowski said St. Andre wrote. "'No one can love you like I love you.'"

In May 2018, the judge revoked St. Andre's $60,000 bond after he tried to send a letter to the victim. After Warren police obtained a search warrant for St. Andre's DNA, the defendant denied the allegations and told police his daughter used his sperm to impregnate herself.

"What he said was that, he was donating sperm to a lesbian couple out of Flint," Detective David Huffman said in November. "And that there were samples in the refrigerator."

Eventually St. Andre confessed that he may have had intercourse with his daughter, Huffman says, and said: "I can't believe I'm going to say this" and told police he woke up to find his daughter in bed with him.

Police say they did not believe St. Andre's story. When the DNA came back, it confirmed that St. Andre was the baby's father. 

"The daughter had the attention of another boy about her age and dad was not happy with it," Huffman said. "And he was saying things like, 'You can't kiss him, you're my wife.'"
