JACKSONVILLE, Fla. -- At an event for Florida Missing Children’s Day, the families of two boys who disappeared four year ago appear with investigators and advocates to show pictures of what the young men would look like at age 17.

Mark Degner was 12 years old and Bryan Hayes was 13 years old when they walked away from Paxon Middle School on Feb. 10, 2005. The two friends are believed to have run away together and despite sightings, no one has heard from them since.

Mark and Bryan are now 17 years old. Age progression pictures of Mark and Bryan were unveiled at a news conference in front of the Police Memorial Building that included the families, police and the Justice Coalition.

"The reason we've gathered here today is not to find two 12-year-old boys -- it's to bring awareness to that these boys that we're searching for are now 17-year-old young men," ," Angie Campbell, Mark's aunt, told the gathering. "We ask for your continued prayers for their continued well-being and safe return."

This is the 10th year for Florida Missing Children’s Day. Each year parents, children, law enforcement and citizens gather to remember those children who are still missing and those who will never come home again.

Gov. Charlie Crist and other notables took part in a similar event held in Tallahassee. The objective of the day is to raise awareness to Florida’s missing children and to educate the public on child safety and abduction prevention.
