The case against anEdmonton man accused of killing his pregnant wifedoesnot add up and leaves too many unanswered questions, Michael White's defence lawyer told the jury Tuesday.

Laura Stevens claimed police began shutting doors on the investigation soon after Liana White went missing because police assumed Michael White was the killer.

White, a 29-year-old heavy duty mechanic, has pleaded not guilty to second-degree murder and committing an indignity to his dead wife's body.

Liana White disappeared in July 2005 and her husband's appeal for the public's help before he was chargedmade national headlines.

The Crown has argued that Michael White killed Liana in their home, cleaned up the blood and then abandoned her naked body in a ditch on the city's northern outskirts.

But Stevens saidthere are still many unanswered questions in this case, including the motive.

"Michael White loved his wife. He gained nothing from this. He lost everything."

Stevens told the jury forensic evidence couldn't pinpoint the time, place or cause of Liana White's death.

"There is something very wrong with this picture," she said.

Stevens pointed out that several Crown witnesses gave testimony that differed from what they originally had told police.

She also said that investigators found nowhere near enough blood in the house for someone to have been stabbed to death.

"Where's the blood?" she asked.

Crown makes its argument

But Crown Prosecutor Troy Coulliardsaid this trial is not about why Liana was murdered.

He told the jury all the evidence that points to White as the killer is not a tragic series of coincidences. He said it points to him because he's guilty, Coulliard said.

"He killed her and he meant to do it," he said.

During the trial, White testified in his own defence, tearfully insisting he loved his wife andwould never hurt her.

He said bloody evidence collected by police could be explained by a serious nose bleed his wife had suffered a few weeks before she disappeared.

But Coulliard saidevidence of bloodstains on the bedroom wall and White's clothes in the garbage bag were consistent with stabbing, not dripping from a nosebleed.

"These were not passive bloodstains dripping from a nosebleed," Coulliard said. "These were projected bloodstains."
