The daughter of a woman murdered by a man from Laos who is among those controversially deported from the US to South Sudan has spoken out about her family’s pain but also to decry the lack of rights afforded to those who were expelled to countries other than their own.

Birte Pfleger lives in Los Angeles and was a history student at Cal State University in Long Beach when her parents came to visit her from their native Germany in 1994 and ended up shot by Thongxay Nilakout during a robbery while on a sightseeing trip. Pfleger’s mother, Gisela, was killed and her father, Klaus, wounded.

Nilakout, now 48, is Laotian and was among eight convicted criminals from countries including Mexico, Cuba, Vietnam and Myanmar who were deported to the conflict-torn African country, amid uproar over Donald Trump’s extreme immigration policies.

In an interview with the Guardian, Pfleger said: “It’s been 31 years living with the irreparable pain and permanent grief, so, on the one hand, I wanted him gone. On the other hand, I’m a historian and I have taught constitutional history. He was denied due process and that’s a constitutional problem.”
