LYNN, Mass. -- A local teenager is helping to get out more information about a missing 5-year-old boy who was last seen in August.

NewsCenter 5's Jim Boyd reported that Giovanni Gonzalez was last seen on Aug. 16 with his father, Ernesto Gonzalez, who is being held at the Middleton House of Corrections on a child endangerment charge.

Teen Helps In Search For Boy

Clear Channel is providing a billboard, free of charge, which will be going up next week in Lynn's Wyoma Square. It will include pictures of Giovanni and his father.

The billboard was the idea of Richard Yearwood, 16, who said he wants to make sure the community does not forget about the child.

"You know, maybe they didn't see the smaller poster and they would be able to see the billboard and know that Giovanni is missing," Yearwood said.

Giovanni's mother, Daisy Colon, said that she dropped Giovanni off for a visit with his father and the boy has not been seen since. She said that she was grateful to learn about Yearwood's efforts.

"He is not even an adult yet, and it is coming out of his heart," Colon said. "It is so noble. It's like my son is reaching out on young people."

Yearwood said that he is optimistic that the billboard may help break the case.

"They see that he is missing, and they will come forward with any information that they may have," Yearwood said.

Anyone with information about the child is urged to call Lynn police at 781-595-2000.
