CANBY, Ore. If Francis Weaver, 31 (pictured right), is convicted in the Sunday killing of a Grants Pass man, he will be part of three generations of murder.

Weaver is the stepson of Ward Weaver (pictured center), an infamous Oregon child killer responsible for the 2002 deaths of 12-year-old Ashley Pond and 13-year-old Miranda Gaddis, both of Oregon City. Ward Weaver pleaded guilty to multiple counts of murder in the deaths, along with attempted aggravated murder and rape in several other cases. He was spared the death penalty as part of a plea deal.

The crimes, however, were not the first in a lineage of murders perpetrated by the Weaver men.

Ward Weaver s own father, Ward F. Pete Weaver Jr. (pictured left) was found guilty and sentenced to death in 1984 for killing two people. He buried one of the victims under a slab of concrete, a crime almost identical to the one his son would commit some 18 years later, according to numerous newspaper reports from the time.

The disturbing irony in the case is Francis Weaver turned in his stepfather, Ward Weaver, for the Oregon City murders. Francis Weaver was hailed as a hero and spoke openly about his role in the arrest of his stepfather.

The whole thing just disgusts me. I d hate to even think that I was brought to this world from a man like that, Francis Weaver said in an interview with Good Morning America in 2002.

Police on Monday named two suspects in the death of 43-year-old Edward Spangler in a reported drug-deal-gone-bad. But on Tuesday, police said Francis Weaver would also be charged for murder in the case even though detectives don't think he was the gunman in the murder.

On Wednesday, KGW obtained court documents that outlined how the suspects stalked and later shot Spangler in the face while trying to steal 15 lbs. of marijuana.

Weaver has an extensive criminal past including several assault charges in recent years. In the latest arrest, he was charged with assault in a domestic violence incident. He was also arrested in January for possession of heroin.
