RIO DE JANEIRO (AP) — A Bolivian woman who pointed out irregularities in the flight plan of a plane that crashed and killed 71 people has traveled to Brazil to seek assistance from prosecutors.

Brazil's federal prosecutors' office said in a statement Tuesday that the woman presented herself at the border city of Corumba and requested help.

According to the prosecutors' office, the woman worked at the Bolivian aviation agency that approved the ill-fated flight Monday between Santa Cruz, Bolivia, and Medellin, Colombia. The prosecutors' office did not name her.

Initial investigations have found the jet's maximum flying range was exceeded.

In the aftermath, several high-ranking aviation officials were suspended in Bolivia.

In total, 71 people died, including 19 members of the Chapecoense soccer club. The team was headed to a match in Colombia.
