GAINESVILLE, Georgia (AP) -- A 37-year-old woman was charged with child molestation after being accused of having a sexual relationship with a 15-year-old boy whom she married last week.The woman also is allegedly pregnant with the boy's child, though paternity hasn't yet been determined, his grandmother and guardian told The Associated Press on Monday."You hear about stuff like this from the TV, but it's not reality," Judy Ann Hayles said. "But (this) happened. And this won't be over because a baby is on the way."Lisa Lynnette Clark was arrested Wednesday and remained in custody Monday. A preliminary hearing is set for November 30.Hayles filed a police report on October 6 when she learned from a friend that Clark was pregnant. About a month later, before authorities made their move, the two were married.In Georgia, a person must be 18 to marry without parental consent or 16 to marry with parental consent. But if the couple has a child or the woman can show she is pregnant, the age requirement doesn't apply.District Attorney Lee Darragh said Georgia law on child molestation says that a person under 16 legally cannot consent to a sexual act. Darragh would not comment further on the case.Hayles said she knew her grandson was spending a lot of time with his best friend's mother, but she had no real objections until she found love letters and lurid photos from Clark.Hayles' grandson had been spending every weekend with Clark's son. In July, the two boys were charged with burglarizing a neighbor's home and sent to a youth detention center for 45 days.Hayles said her grandson during that stay received the letters from Clark, along with seductive photos of her posing on top of a mantle and in a bikini.Hayles said she hopes to get an annulment or a divorce for her grandson.Hayles, who lives on the outskirts of this northeast Georgia town, said that if the baby is shown to be her grandson's, she's not optimistic about the teen's future."This child's life is down the tubes," she said. "What's he going to do with a kid? He's not even old enough to buy groceries."Copyright 2005 The Associated Press.
