SEATTLE – A 23-year-old man was arrested Friday in a brutal attack that killed one woman and injured another as they slept in their home.
Isaiah M.K. Kalebu was taken into custody for questioning and would be booked into jail for investigation of murder, said Sgt. Sean Whitcomb.
Earlier Friday, police released a photo of Kalebu, describing him as their primary suspect, and saying he was the person shown in a surveillance video they also released. A transit bus driver told police he'd seen a man fitting the description and Kalebu was found with his pit bull in Seattle's Magnuson Park.
Kalebu is suspected in the July 19 murder of Teresa Butz, 39, and the wounding of her partner, a 36-year-old woman, who was injured when they were stabbed by a man who apparently crawled in through a window in Seattle's South Park neighborhood.
Police did not disclose any details about evidence linking Kalebu to the stabbings.
The Seattle Times said Kalebu was scheduled for trial on domestic violence charges Aug. 6 in King County, accused of threatening to kill his mother while he lived with her in 2008. Pierce County sheriff's spokesman Ed Troyer confirmed Friday to The News Tribune that Kalebu was questioned, but not arrested or charged, after a July 9 Tacoma-area fire that killed two people, including Kalebu's aunt, Rachel Kalebu, 61.
Troyer also confirmed that detectives continue to consider him a "person of interest" in the case.
"Nobody's been ruled in or out," said Troyer, who did not immediately respond to Associated Press phone and e-mail messages Friday night.
Court records in the King County case show Kalebu was charged with felony harassment and first-degree malicious mischief. Prosecutors say he threatened to kill his mother after she confronted him in March 2008 for not taking prescribed medication for "bipolar and manic-depressive" conditions, according to court documents.
A state psychologist evaluation in 2008 found he "did not have the capacity to rationally understand" the case against him at that time.
Seattle police have called the South Park stabbings one of the most brutal crimes they've seen. The victims eventually managed to get outside after the attack.
Before she died, Butz talked to a neighbor, Albert Barrientes, saying of the attacker: "He told us if we did what he asked us to do, he wouldn't hurt us. He lied, he lied."
Butz's partner, who has not been identified, was released Monday from Harborview Medical Center.
