President Trump said on Monday that the kidnappers of a California woman in Uganda must be brought to justice.

“Uganda must find the kidnappers of the American Tourist and guide before people will feel safe in going there,” Trump posted on Twitter. “Bring them to justice openly and quickly!”

Kim Sue Endicott and her Ugandan guide Jean-Paul Mirenge Remezo were released on Sunday — five days after being nabbed while on safari in Queen Elizabeth National Park and held hostage by armed captors who demanded a $500,000 ransom.

There were conflicting reports on Monday whether the ransom had been paid.

Ugandan police spokesman Fred Enanga said during a news conference Monday in Kampala that a ransom had not been paid, the Associated Press reported.

“I have indicated to you that we don’t do ransom,” Enanga said.

But an official with Wild Frontiers Uganda Safaris, which organized Endicott’s trip, said she was released and “not rescued” after the ransom was paid.

“Otherwise she wouldn’t be back,” the official said, speaking anonymously.

Endicott’s kidnappers are at large and Ugandan President Yoweri Museveni said the country’s security forces “shall deal with these isolated pockets of criminals.”

Officials with the US Embassy were involved in gaining the release of Endicott, the owner of a skin care shop in Costa Mesa, Calif.

Trump reacted to their release on Sunday.

“Pleased to report that the American tourist and tour guide that were abducted in Uganda have been released. God bless them and their families!” the president tweeted.
