Two men who allegedly fired shots at a group of high school students, wounding two, following an argument at Vancouver’s Marine Park in September were in Clark County Superior Court this week.Mykola Kovalchuk, 20, of Gresham, Ore., appeared Thursday on suspicion of two counts of attempted first-degree murder, 11 counts of first-degree assault with a deadly weapon and one count of drive-by shooting. A co-defendant, Dmitriy Yurchenko, also 20, of Portland appeared Tuesday on the same charges.Vancouver defense attorney Steve Thayer was present Thursday on behalf of Kovalchuk and argued that the probable cause affidavit, which has been sealed since the men’s arrest warrants were issued in mid-October, should be unsealed.Deputy Prosecutor Aaron Bartlett agreed to unseal both cases. He added that there’s a separate ongoing investigation but would not elaborate further.A group of 11 high school students were leaving a bonfire shortly before 11 p.m. Sept. 29 at the park, 4501 S.E. Columbia Way, when they encountered a group of 10 to 15 Eastern European males, including Yurchenko and Kovalchuk, in the parking lot. Some of the males were blocking a female student’s car from leaving, according to the probable cause affidavit.The female student asked the group to move so she could back out of her parking spot, but they refused. The girl became impatient, she said, and told the group to move, using a derogatory term. In response, one of the males wanted to fight, the affidavit states.
