"Natsumi’s boyfriend at the time, Jay Vergara, described her as a dedicated student working hard to improve her English. She often stayed at his place in East Vancouver, he told the court. The last time he saw her was the morning of Wednesday, Sept. 7, 2016 when he dropped her off at the SkyTrain station."

But the Crown laid out the case against him that will include evidence from Warren Schneider about his brother’s relationship with Kogawa, CCTV footage of William from the homeless men’s shelter he lived in in August and September 2016, testimony from the shelter staff of his relationship with a Japanese woman, her credit-card statement showing purchases of vodka and snacks the last day she was seen, and a police interview with William in which he discussed her death and gestured holding his nose.

Warren is also expected to tell the trial William had met Kogawa three times. The day they last met they were on their way to Stanley Park to have sex in the tent, but they didn’t get that far, instead having a few drinks and taking some medication, said Proulx. William then told Warren that Kogawa had a prior engagement and had to leave, he said.

The trial will also hear that a folded triangular piece of cloth was found in Kogawa’s anus.
