TUCSON, AZ - Police documents just released detail new information in the case of missing Isabel Celis of Tucson.
According to an ABC News report Friday on Good Morning America, more than 500 pages of police records go over "apparent blood" found during the investigation and a person who possibly owed money to Isabel's family.
The 6-year-old girl was last seen in her bedroom around 11 p.m. on April 20 and was discovered missing around 8 a.m. the next day.
In regards to the "apparent blood," the records say it was in photos taken in the home during the investigation. But the documents reportedly didn't specify which room the photos were taken in.
ABC News, however, reported that it may have been Isabel's bedroom based on a blueprint of the house.
ABC News also said that in a police document, a witness claimed that "a guy staying with the family owed them a lot of money and that's why she was taken."
Multiple officers also noticed footprints on a utility box behind the home, which could have been used to hop over the wall surrounding the Celis home, according to ABC News.
And a car in front of the house was also searched and investigators removed many items from it.
Isabel's father reportedly fell asleep watching a prerecorded Arizona Diamondbacks game and woke up around 5 a.m. ABC News reported.
And Isabel's mother left for work around 7 a.m.
In the 911 call with Isabel's mother, she said she didn't check on Isabel before work.
Isabel was discovered missing an hour after she left.
