The anti-gay Westboro Baptist Church intends to picket the funeral of the two Powell boys murdered Sunday by their father, blaming their deaths on Washington state's legalizing of same-sex marriages, The News Tribune in Tacoma reports.

Occupy Seattle plans to counterdemonstrate.

Gov. Chris Gregoire is likely next week to sign the measure, which finished clearing the Legislature on Wednesday.

Margie Phelps, daughter of the Westboro Baptist Church's founder, tweeted Wednesday night that members of the small Topeka church will be at the Saturday morning service for Charlie, 7, and Braden, 5. She wrote that the protest is to "remind" Gregoire "they died because of her rebellion," a reference to her support of same-sex marriages, the paper writes.

Later, in a tweet referencing a news story about legalizing same-sex marriage, Phelps wrote, "This is why God's cursed you w Josh Powells blowing up kids."

Westboro came to prominence by picketing U.S. military funerals with provocative signs, which courts have upheld. The church, consisting mostly of the Phelps family, blames troops' deaths on U.S. tolerance for homosexuality.

Occupy Seattle said its members don't intend to disrupt the funeral, but want to "protect it from Westboro's abhorrent message," the News Tribune writes.

ABC News has a video interview with the boys' social worker about their final moments. After she dropped them off at their father's home for a supervised visit, Josh Powell attacked the boys with a hatchet before blowing up his gasoline-soaked house.

Logs of the social worker's 911 call show an eight-minute delay in sending sheriff's deputies to the house in Graham, Wash.
