A 51-year-old man in Oakland, California, was killed while protecting his wife and their unborn child during a home invasion robbery.

On May 22, at least one man stormed Hoan Lieu’s residence in the 4100 block of Carrington Street in East Oakland. They threatened his 38-year-old and pregnant wife, Kat, who was watching TV. Lieu, who was in another room, rushed to save his wife but was shot dead. The robbers got away.

Speaking to East Bay Times, Lieu’s younger brother, Chris, said that his brother protected his wife, whom he met in China three years ago.

“In my mind he was a hero. He was someone who gave his life for his wife and unborn child,” Chris told the publication.

The Lieu family immigrated from China in the 1980s. They were thrilled when Hoan, who was also called “Harry,” met the love of his life there.

The pair married in December 2015. Their first baby — who will be named Benjamin — is due in August.

“He was happy about his future. He was looking forward to it. He was working even harder after Kat got pregnant,” said Chris.

Lieu drove for Uber and Lyft, worked in construction, and installed sound equipment for various events.

In the wake of the tragedy, Chris launched a GoFundMe page to help the family get through and aid Benjamin’s future. The campaign has collected $34,422 out of its $100,000 goal in the first five days.

For now, Kat finds solace and home with her husband’s family. Chris said she can stay with them for as long as she needs.

“Kat is grieving hard at Harry’s passing. Not many moments pass without her thinking about my brother and crying her eyes out but she also knows not to let the grief overwhelm her lest it harm their unborn child. She is doing all she can to hold it together for the sake of Benjamin.

“My brother was the primary provider for his family and now he is gone. Kat and Benjamin are in need of financial assistance. Any contributions you give will go to supporting Kat and Benjamin through this darkest of times and give some security to baby Benjamin’s future.”

A $15,000 reward has been placed for anyone with information leading to the suspects’ arrest. Police and Crime Stoppers may be reached at (510) 238-3821 and (510) 777-8572, respectively.
