Sean Thomas

For the second time in a week, a Jamestown infant has been critically injured by an adult.

Sean. L. Thomas, 26, of Jamestown, was charged with first-degree strangulation, second-degree assault and endangering the welfare of a child after officers responded to a home on the city’s north side on Monday for a report of an 8-month-old child not breathing. The child was taken to UPMC Chautauqua before being taken to an out-of-town hospital for treatment of critical, life-threatening injuries.

According to a police report, Thomas allegedly shook and then strangled the infant.

Thomas was charged and taken to the city jail until he can be arraigned. Further charges are expected.

Jamestown police are working with the Chautauqua County District Attorney’s office on the investigation.

On Monday, city police announced charges against another Jamestown man who allegedly caused the death of a 16-month-old child he was babysitting. Jamestown police were notified April 15 of a suspicious death of a child that occurred April 13 in the city. An investigation showed Matthew E. Nuttall, 25, allegedly caused the death of a 16-month-old child by blunt force trauma. Nuttall was charged April 17 with second-degree manslaughter and was arraigned April 18 by Judge George Panebianco before being sent to the Chautauqua County Jail on $500,000 cash bail or $1 million property bond.

A preliminary hearing was held Monday, after which Nuttall was held for action by a Chautauqua County Grand Jury. Nuttall remains in custody.
