The FBI has increased the reward for information in a 20-year-old kidnapping cold case.

Joshua Keshaba Sierra Garcia was four months shy of turning three when he was kidnapped in Mexico City on 12 August 2003.

The toddler was visiting the country with relatives that planned to have him baptised during their stay. But a kidnapping attack left Joshua’s 14-year-old babysitter dead and more than 20 years after the ordeal, his family still searching for answers.

Despite a previous arrest made following a money drop, law enforcement currently has no information regarding his whereabouts.

The FBI is now offering $20,000 for anyone who comes forward with information that leads to Joshua’s recovery “alive or deceased.”
