The Philippine Court of Appeals has upheld a guilty verdict on a U.S. Marine for killing a transgender woman nearly three years ago, a case that stirred debate over the U.S. military presence in its former colony.

A lower court had found Lance Corp. Joseph Scott Pemberton guilty of killing Jennifer Laude in a hotel in Olongapo, outside a former U.S. Navy base northwest of the capital, in 2014.

He was jailed for between six and 10 years on a Philippine military base.
