SUNDRIDGE, Ont. - The family of a man who was charged with killing a provincial police constable is asking that memorial donations be made to the dead officer's family.

Const. Vu Pham was shot last Monday after pulling over a pickup truck in rural southwestern Ontario and died later that day in hospital.

Fred Preston, a retired logger and one-time politician, was charged with first-degree murder in Pham's death before he too died last Thursday after his family took him off life-support.

Preston, 70, was shot during the confrontation with Pham and another Ontario Provincial Police officer.

A funeral will be held for Preston on Tuesday in the northern Ontario community of Sundridge and his family is asking mourners to donate to a fund for Pham's family.

Pham, a 37-year-old married father of three sons, came to Canada from Vietnam when he was a boy and spent part of his youth in Sundridge.

The province's Special Investigations Unit, which probes incidents between police and civilians involving serious injury or death, is investigating the circumstances around Monday's shootout.

On Friday, Pham was remembered as a "modern-day hero" and a great father at his funeral.

Pham's widow and children spoke of their love for the officer, whose funeral in Wingham was attended by thousands of police officers from Canada and the United States.

In the funeral program, Pham's wife said her husband was the love of her life, and that when he left for work on Monday morning, she didn't expect that would be their final goodbye.

Pham was taken in as a boy by Dan Thompson, a southwestern Ontario pastor who later moved to northern Ontario, where Pham and his three new siblings were raised.

He was the force's 104th officer killed in the line of duty since its inception 100 years ago.

Preston was a former reeve of Joly township, located in Sundridge.

"If desired, memorial donations to a trust fund in support of Const. Vu Pham's children would be sincerely appreciated by the family," reads Preston's death notice.

Residents have called it a startling coincidence that both Preston and Pham lived in the community, some 375 kilometres from the scene of the shootout, when Pham was a boy.
