The defense team for Conner Schierman, the Kirkland man facing the death penalty for allegedly killing a family of four in 2006, called its last witness Monday after more than two weeks of testimony.

Schierman, 28, did not testify.

King County Senior Deputy Prosecutor Scott O'Toole will start calling rebuttal witnesses Monday afternoon. Closing arguments could be given as early as Wednesday morning.

Schierman is charged with four counts of aggravated murder and one count of arson. If the jury finds him guilty of aggravated murder a second trial will immediately commence. In this second trial, called the "penalty phase," jurors will determine whether or not Schierman should face the death penalty.

Schierman is accused of fatally stabbing his neighbors Olga Milkin, 28; her sons Justin, 5, and Andrew, 3; and her sister, Lyubov Botvina, 24, in Milkin's home on in July 2006. The four victims' bodies were then burned using gasoline.

Firefighters, crawling through the smoke and soot in search of survivors, found the sisters' nearly nude bodies propped on a futon, according to court testimony.

After his arrest, Schierman told authorities he awoke from an alcohol-induced blackout to find himself covered in blood "amongst the deceased," according to court documents. His face and neck had deep scratches, and his left arm bore a puncture wound.

In court last week, a psychologist called to the witness stand by the defense told jurors that Schierman awoke inside the Milkin home on July 17, 2006, but doesn't recall why he was in the house or what happened to the four victims.

Jurors also heard last week that Schierman is believed to have consumed more than a liter of vodka in the hours leading up to the slayings. A toxicologist testified that after reviewing how much Schierman drank -- three bottles of Ketel One vodka -- his weight, and the time during which the alcohol was consumed he believes Schierman had a blood-alcohol content of 0.35. Washington's legal intoxication threshold is 0.08 percent.

The trial started on Jan. 20.
