Five people have been arrested on suspicion of homicide in the March killing of a woman shot inside her ride-share<\/a> during a parking lot shootout on Auburn Boulevard, said Sacramento County Sheriff\u2019s officials Thursday.<\/p>\n Among the suspects was Juan Colmenero, 20, of Emeryville, who investigators said fled to Puerto Rico following the deadly shooting. Sheriff\u2019s detectives on Wednesday arrested Colmenero at San Francisco International Airport, sheriff\u2019s officials said.<\/p>\n Four others \u2014 Kymani Agbouti, 18, of Vallejo; Avante Washington, 18, of Antelope; and two juveniles from Oakland and Sacramento \u2014 were arrested April 20 in the killing, according to the Sheriff\u2019s Office. A five-week investigation of the Old Foothill Farms incident led detectives to the suspects, officials said.<\/p>\n Washington was held without bail at the Sacramento County Main Jail on suspicion of murder and conspiracy. He was scheduled to appear in Sacramento Superior Court on Wednesday. Booking information for Agbouti and Colmenero was not available Thursday.<\/p>\n The deadly shooting happened about midnight during a \u201cpop-up\u201d party late March 15 at a building in the 4300 block of Auburn Boulevard killed 18-year-old Arianna Arissara Hissom, according to Sacramento County Coroner\u2019s Office.<\/p>\n Hissom, who was born in Okinawa, Japan, is survived by her parents and two younger sisters<\/a>, according to an obituary published in the Santa Cruz Sentinel.<\/p>\n Investigators later learned Hissom and her male passenger, who was wounded, were caught in a crossfire as a group of four or five men grabbed weapons from a vehicle and began firing at each other. As many as 70 shots were fired in the parking lot shootout, deputies said.<\/p>\n The two victims, who did not know the gunmen, were trying to leave the parking lot during the gunfire, the Sheriff\u2019s Office said. The male passenger was hospitalized with gunshot wounds but was expected to survive, officials said.<\/p>\n The shootout happened at a \u201cpop-up\u201d party similar to one earlier in April at Howe Park<\/a>. Four people were wounded in a shooting at the park in Arden Arcade, where several hundred people had gathered as law enforcement broke up the crowd. A woman and three men, all in their 20s, were shot, authorities said.<\/p>\n Authorities have no suspects in that shooting.<\/p>\n This story was originally published April 30, 2026 at 8:43 AM.<\/p>\n
