Six years since the disappearance of three brothers, new images show what they might look like today.

Alexander, Andrew and Tanner were 7, 9 and 5 years old when they went missing a day after Thanksgiving 2010. Renderings posted on Monday, Dec. 19, the National Center for Missing and Exploited Children's website show them at ages 13, 15 and 11, respectively.

They last were seen at their southeast Michigan home in Morenci.

Mother Tanya Zuvers said there's a reason why police investigate the case as a homicide, according to WXYZ-TV.

The boys' father, John Skelton, is serving a 15-year sentence for unlawful imprisonment for the three boys' disappearance.
