They were both last seen near the 1500 block of NE 191st Street.

“They were hanging out at somebody’s house. I saw them.  I thought they were just playing so I just left and I haven’t seen them since that day,” said a child at the park.

Police believe the two may be together.

Investigators said the older child has run away before.

“Michelle has done this in the past. This time a little different where she took her young sister who’s 8-years old with her,” said Daniel Ferrin with Miami-Dade Police.

Neighbor Jack Teachman who is close to the father said learning the children are gone surprised him.

“I spoke to the father last night. He called me to go feed the dogs. I fed the dogs and gave water.  He never mentioned anything about the daughters missing,” said Teachman.

Investigators said the children’s grandmother in North Miami has custody of the girls.  Detectives are checking to see if the girls are with the parents who do not  have custody.
