In many articles, I've read that Amber Robertson, Amiah's mother, reported her missing. But as osu said, I remember reading that Amiah's bio dad had called the police concerned that RL was abusing both of Amber's sons. I don't remember the timing of that call. I'll keep looking for that article. The section of an article saying Amber reported Amiah missing to the police and the source are below:
Amiah Robertson went missing last week. Amber Robertson, Amiah’s mother, reported her missing to police on Saturday, but Amber told police she actually went missing last Thursday.
Amber says she didn’t think Amiah was in danger—that’s why she says she waited two days to report it.
Yesterday, police issued a Silver Alert, saying Amiah is in extreme danger. Authorities say the family has been telling them conflicting stories about what happened.
Amber says the baby girl was last seen at the babysitter’s house on the near west side. Detectives searched the home for hours on Tuesday, focusing on a detached garage, but it’s unclear if they found anything.

Why a Silver Alert, not an Amber Alert, was issued for 8-month-old girl missing from Indy
I believe the same man, LH, fathered both of Amber's children. The
ex-boyfriend/Motel 6 date is RL who is currently in jail. Amber claims RL had Amiah and was supposed to take her to the baby sitter's house.
