BETHLEHEM (Ma'an) -- A young Palestinian-American woman is among the dead after a gunman opened fire in a US theater last Friday, killing 12 people and injuring 70, her family confirmed on Tuesday.

Jessica Ghawi, 24, was an aspiring journalist who had moved to Aurora, Colorado to pursue a broadcast career, according to her brother Jordan, 26, who lives in Texas.

Jordan told Ma'an that Ghawi was a Palestinian-American. "My father is a Christian Arab from Palestine," he said Tuesday.

The Palestinian mission in Washington said it was mourning all the victims.

"Our thoughts and prayers go out to Aurora. We mourn the loss of all of the lives, including Palestinian Jessica Ghawi," the general delegation of the PLO to the US wrote on Twitter.

A month before the shooting, Ghawi had moved to the Denver area from San Antonio to intern with a sports radio station, according to US media reports.

She is expected to be buried in her hometown on Saturday.

On Monday, suspected shooter James Holmes made an initial court appearance. He is expected to be formally charged with the killings on July 30.

More than a dozen victims remain hospitalized.
