Court upholds Iowa mom's murder conviction

DES MOINES, Iowa – The Iowa Court of Appeals has upheld the murder conviction of a woman who drove her two young sons to a pond and cut their throats, killing one of them.

Michelle Kehoe of Coralville is serving a life sentence for the Oct. 26, 2008 death of her 2-year-old son, Seth. She also is serving a 25 year sentence for the attack on her son Sean, who was 7 years old at the time. Kehoe initially told investigators she and her children were attacked by someone else.

Kehoe appealed her conviction, claiming her lawyer was ineffective and failed to object to jury instructions and to challenge constitutional issues related to her case.

The appeals court rejected Kehoe's arguments Wednesday.

Telephone messages left for attorneys in the case were not immediately returned.
