AURORA, Colo. -- Family members and friends of an apartment manager who was found stabbed to death in Aurora said they hope a big reward will help police find her killer.

Police received a report of a critically injured woman just before noon on March 3, and found 45-year-old Lyndsay Pham in her office on the ground floor of the Descanso Plaza Apartments at 16th and Kingston. She’d been stabbed several times.

“This is a big loss,” said Joseph Nguyen, a close family friend. “It’s a loss for her three kids and her loving husband.”

Pham’s family is offering a $15,000 reward for information that will help lead to the arrest and conviction of the person or persons responsible.

Police are offering $5,000, which brings the total reward package to $20,000.

“We’re hoping that someday justice will be done for her,” Nguyen said.

Pham came to the U.S. shortly after the Vietnam War.

“Once she got here she helped others without asking for anything in return,” Nguyen said. “She helped other Vietnamese immigrants find housing, jobs and medical help.”

“She knows the English language,” added longtime friend Vi Pham. “So she helped immigrants fill out forms and she took them to the office to do those things.”

“We miss her very much,” said Father Gregory Vi Tran of Queen of Vietnamese Martyrs Catholic Church in Wheat Ridge. “She worked hard at this parish and put in a lot of effort helping to raise funds.”

“It’s just unbelievable how something so horrible could happen to such a kind person,” said longtime friend Louis Tran. “I still can’t believe it happened.”

Police aren’t speculating on a motive.

They hope the reward offer will encourage someone who knows something about this case to come forward.

A funeral Mass for Pham will be held at 10 a.m. Saturday at Queen of Vietnamese Martyrs Catholic Church.

Burial will be at Mt. Olivet cemetery.
