Organizers of an international robotics competition in the U.S. capital believe the disappearance of six teens from Burundi may have been "self-initiated."
"There were indications that the students' absence may have been self-initiated, including leaving all their keys in their mentor/chaperone's bag and the removal of students' clothes from their rooms," FIRST Global said in a statement.
Police now say that two of the six were seen crossing into Canada, and they don't suspect foul play with any of them.
Two of the six teens from Burundi who competed in the International Robotics Challenge in Washington, D.C. and who reportedly went missing on July 19, were seen entering Canada, Washington, D.C., police told Suzanne Kennedy of our affiliate WJLA on Thursday.
The other four teens appear to be okay, according to police, and are reportedly with members of their family in the United States.

Metropolitan Police released the names and photos of the teens on their Twitter page on Wednesday.
Audrey Mwamikazi, 17, Don Charu Ingabire, 16, Aristide Irambona, 18, Nice Munezero, 17, Kevin Sabumkiza, 17, and Richard Irakoze, 18, are all missing.
Burundi is a small country in east Africa.
The teens disappeared from the competition before it ended, and arrived in the country last week for a robotics competition at DAR Constitution Hall. The event was held from July 16 to July 18.
The teens were last seen at 5:30 p.m. on July 18 during the event's closing ceremony, according to ABC7's Suzanne Kennedy.
More than 150 countries were represented in the competition also described as robotic Olympics. Teams went head-to-head using science, technology, math and engineering.
On July 19, a member of the group contacted a volunteer from the organization that sponsors the robotics competition informing them that the teens were missing. Metropolitan Police got involved and canvassed Constitution Hall in their search for the team.
The teens were in town temporarily for the competition and have one-year visas, according to Kennedy.
