MARION, Ind. -- (WISH/CNN) -- Nicholas Deon Thrash was no stranger to the young girl he's accused of molesting and impregnating.
"It's not the type of person that you'd think would do something like this," said the girl's grandmother, who didn't provide her name.
In fact, he was living with the girl's mother.
Thrash was arrested Wednesday on 10 felony counts of child molestation, WTHR reported.
Extended family say they met Thrash multiple times.
"We invited him into our home. He helped my husband all he could," the girl's grandmother said.
But now he's behind bars, and family says the young girl is 20 weeks pregnant.
"Now her whole life has changed. She's scared, being this far along and having to carry this baby," the girl's grandmother said.
Family members are caring for the girl while her mother is in jail in connection with the case.
