Flowers and teddy bears have been left at the front gate of a waterfront mansion that was gutted Monday by a massive fire, Tuesday, Jan. 20, 2015, in Annapolis, Md. Relatives of six family members who remain unaccounted for after the fire believe they were inside at the time of Monday's blaze, a fire official said Tuesday.

The big sister wanted to be known as a gamer, and she loved making videos with her pet guinea pig, Oreo. Her 6-year-old brother wanted to build robots when he grew up.

Their cousins, a pair of blue-eyed, towheaded sisters, were a year apart but looked more like twins. The older girl just knew she was going to be famous one day, and her little sister loved Taylor Swift.

All four are now believed dead.

Their parents believe the children, ages 6 to 8, along with their grandparents, were inside a mansion near Annapolis when a massive fire turned the home into ashes Monday. Crews have found four bodies in the rubble and are still searching for the other two Friday. The official identities of the bodies are pending autopsies.
