A Ridgeville couple whose infant boy was fatally mauled earlier this year pleaded guilty today to stealing a relative’s wedding ring, according to a court official.

During a Summerville Municipal Court hearing this morning, a judge ordered Quintin McGrew, 29, and Chantel McGrew, 24, to pay a $750 fine each.

The ring’s owner and Quintin McGrew’s cousin, 27-year-old Danelle Moore of Summerville, said the McGrews watched her ailing husband while she spent a week out of state in July.

Moore returned and couldn’t find the 10-karat gold band encrusted with a dozen small diamonds. She thought she had left it on an entertainment center.

In arrest affidavits, the Summerville Police Department said the McGrews were later seen on surveillance video selling the ring for $15 at a pawnshop. The piece of jewelry was valued at $270.

They were arrested Aug. 27 on a charge of petty theft.

Moore said the married pair betrayed her trust: She helped support the McGrews after their 2-month-old boy and Moore’s godson, Aiden, was killed by the family’s Labrador-retriever mix on April 20.

Quintin McGrew faces a charge of unlawful conduct toward a child in connection with the death.

They also face allegations that they exposed Quintin McGrew’s 7-year-old daughter to homemade pornographic films and their own sexual tryst. A criminal investigation into the girl’s statements remains open.

Moore said she’ll continue to fully support the couple and the surviving children: the girl and their 2-year-old son.

She asked for restitution during the court hearing, but it was denied because her stolen ring had been returned.

“I hope they learned a lesson,” she said after appearing in court. “If they ever need me to do anything for those kids, I will help. But they are not welcome in my house.”
