MARSHFIELD, Wis. (AP) -

Two teenagers have been arrested in the attempted robbery of a 96-year-old grocery store owner in Marshfield, according to police.

A 13-year-old Marshfield boy walked into Wolf's Grocery on July 15, flashed a knife and ordered Margarette Wolf to open her cash register, authorities said. Wolf told the boy that she wouldn't hand over the store's cash, but that he could take all the Tootsie Rolls he wanted.

The boy fled without a dime. A 17-year-old boy, who police say encouraged the younger boy to commit the crime in order to get gas money, was also arrested.

"I'm glad they got the 13-year-old, because if he gets the right kind of help, he probably won't do this again," Wolf told the News-Herald Media. "He should know that's the wrong thing to do."

The younger boy has been referred to Wood County juvenile authorities, Marshfield Police Chief Gary Jepsen said.

"We don't know what the circumstances are going to be if he's referred to adult court, and we want to wait to make a determination whether that is going to happen," Jepsen said.

Initially, Wolf said she wasn't going to report the incident to police, but changed her mind after thinking he might try to rob an elderly person's house.

If Wolf had her way, she told the newspaper, the 13-year-old would be in the store on his hands and knees, scrubbing the floors with a toothbrush.
