When a dog fatally mauled her godson this spring, Danelle Moore said she stepped in and offered emotional support to the child’s grieving parents.

So when Moore’s husband had surgery this summer, she welcomed Quintin and Chantel McGrew to return the favor. While Moore left town to help another family member, the McGrews stayed with her husband as he recuperated, she said.

But Moore said her cousin and his wife betrayed her trust and stole the wedding band she had left behind. Summerville police said the McGrews later sold the ring for $15 at a pawnshop.

Moore had paid more than $400 for the 10-karat gold band encrusted with a dozen small diamonds.

“I support them in what they’re going through — don’t get me wrong,” Moore said Friday. “But I don’t support them for what they did to my household.”

Quintin McGrew, 29, and Chantel McGrew, 24, were arrested Aug. 27 on a charge of petty theft in connection with the late July incident. They were released the same day on bails of about $1,000.

Neither was booked into the county jail.

Attempts to contact them were not successful, and their attorney, Andy Savage of Charleston, declined to comment.

For the McGrews, it’s the latest in a series of legal troubles since their 2-month-old son, Aiden, was killed April 20.

In that incident, Quintin McGrew faces a charge of unlawful conduct toward a child. Investigators said he was asleep inside their Sandpit Drive home in Ridgeville when the family’s Labrador retriever mix snatched Aiden from a bouncy swing.

Then in early August, the couple were accused by Chantel McGrew’s 7-year-old daughter of having a sexual threesome and exposing the girl to homemade pornographic films.

The McGrews denied that report, chalking it up to the girl’s propensity to make up stories. But it resulted in state officials removing the girl and their 2-year-old son.

At the time, the McGrews told The Post and Courier that they just wanted “to be left alone.”

The children were returned to their custody this month, when the S.C. Department of Social Services determined that the accusation was unfounded.

Obtained this week, paperwork from the agency stated that the parents had exposed their children to sex acts but that their intent wasn’t known.

State workers also “explained (to the McGrews) the importance of ensuring children are not subject to such acts.”

But Dorchester County sheriff’s Lt. Tony Phinney said a criminal investigation is still “open and active.”

The most recent report was filed with the Summerville Police Department in late July after Moore returned from a weeklong trip to Georgia and found her wedding band, which she had left on an entertainment center, missing.

Moore, who introduced the would-be couple years ago, said she had welcomed the McGrews to stay at her Trolley Road apartment at other times, including when Chantel McGrew was pregnant.

“I let them stay here for months at a time,” Moore said. “But when I got back this time, my ring was sitting in a pawnshop.”

Arrest affidavits stated that surveillance cameras captured the two selling the ring at a Money Man Pawn Shop on Dorchester Road. Moore said a friend tipped her off that the ring, whose current valued was pegged at $270, had shown up at the store.

“I called them, and they said they didn’t steal anything from me,” Moore said. “I just hope it was worth 15 bucks they got for it.”
