Detectives interviewed three of five people in the video; plan to talk to two others.
The group of people was walking near the home of 6-year-old Isabel Celis the morning she
was reported missing. Tucson police would not disclose details of the conversation.
Cops say it's not unusual for people to be walking in the area in the early morning areas because there are nearby nightclubs. Detectives are also reviewing witness statements they gathered in the early days of the investigation.
Dozens of tips are still being investigated.
Previous story from Fox 10:
TUCSON – There are still no major breaks in the case of a little Tucson girl who was reported missing from her home the morning of April 21.
6-year-old Isabel Celis was last seen when her parents put her to bed the night before.
The next morning she was gone. Her bedroom window was open and the screen had been removed.
Detectives are continuing to follow up on leads and reviewing their notes.
Meanwhile, the reward for Isabel’s safe return has been raised to $50,000.
At a media briefing on Saturday, Tucson police Lt. Fabian Pacheco said the agency continues to receive eight to ten tips an hour.
Police have also heard from one of five people seen in a surveillance video taken from a church in Isabel's neighborhood in the early morning hours of the day she disappeared. Detectives will interview the man to see if he or any of his companions saw or heard anything that might help solve the mystery.
Tucson police have also alerted law enforcement authorities in Mexico to be on the lookout for Isabel.
