Update 8:45 a.m. Monday:
The suspect in the Sunday slaying near downtown Anchorage was taken into custody early Monday after a SWAT operation in the 1600 block of Juneau Street, police said after the hours-long standoff.
"The suspect barricaded himself inside with his family members and continued to ignore officers' commands to exit," police said.
Kuach Chuol Kuach, 20, surrendered about 5:45 a.m. without incident, police said. He was wanted for the killing Sunday of Devan McDonald, 22, in an apartment on East Ninth Avenue.
Police received a tip around 11:15 p.m. Sunday that Kuach was in the Juneau Street residence.
"Detectives believe Kuach is the lone suspect in this investigation and are not looking for additional suspects," police said.
A man was found shot and killed in an apartment on East Ninth Avenue on Sunday, according to police.
The shooting death is this year's 34th homicide, matching last year's tally, a record-high number.
"An adult male was found inside an apartment with a gunshot wound to the upper body. He was pronounced dead at the scene," the release said.
At midafternoon Sunday, a green and yellow apartment building on East Ninth Avenue, just west of Gambell Street, was blocked off with yellow crime tape. The APD sergeant on the scene declined to comment.
"We're still gathering information and talking to witnesses," said MJ Thim, an APD spokesman. "This is not random, this is an isolated incident. There is no threat to the general public."
As of Sunday evening, the victim had not yet been identified.
