EUREKA, California — The Humboldt County Sheriff's Office has named two 19-year-olds and obtained arrest warrants in the Myrtletown house shooting — a direct advance on the position a day earlier, when deputies said the November 3 attack on a Harwill Court home was targeted, nobody was hurt, and no suspects had been identified. In a release issued on November 4, the Sheriff's Office said detectives from its Major Crimes Division had identified Tyler Peter Colegrove, 19, of Hoopa, and Alyssa Regina Hansen, 19, of McKinleyville, and that arrest warrants have been issued for both. Colegrove is wanted on an attempted-murder charge; the Sheriff's Office warns that both should be considered armed and dangerous and tells anyone who sees them not to approach and to call 9-1-1. Warrants are allegations, not convictions: neither Colegrove nor Hansen has been found guilty of anything in this case.
The shooting itself happened in the small hours of Tuesday, November 3, 2026. At approximately 2:36 a.m., the Sheriff's Office Emergency Communications Center received multiple 911 calls reporting gunfire in the area of Circle Drive in Eureka, in the Myrtletown area east of the city. Deputies who responded located a residence on Harwill Court that had been struck by gunfire. No injuries were reported — the people inside the home were unhurt — and the Sheriff's Office said in its first release that preliminary information indicated a targeted shooting, not a random attack on the street. Detectives then took over the case, and within about a day the office moved from 'no suspects' to named suspects with warrants.
The charges against each suspect
Colegrove is wanted on three California Penal Code counts: PC 664/187, attempted murder; PC 422(a), criminal threats; and PC 182, conspiracy to commit a crime, the Sheriff's Office release says. Hansen is wanted on a single count: PC 182, conspiracy to commit a crime. The release does not say what role investigators believe each person played — who is alleged to have fired, who is alleged to have threatened, or what the pair are alleged to have planned together — and it does not describe a motive or any connection between the suspects and the people in the Harwill Court home. Anyone reading the warrant list should keep that gap in mind: the charges name the laws, not the story, and the story is what a court would have to hear.
“Armed and dangerous”: what the Sheriff's Office is asking the public to do
The Sheriff's Office states plainly that both individuals should be considered armed and dangerous. Anyone who sees Colegrove or Hansen is urged not to approach them and to call 9-1-1 immediately. Anyone with information about the investigation or the pair's whereabouts can call the Humboldt County Sheriff's Office at (707) 445-7251 or the Sheriff's Office Tip Line at (707) 268-2539. The office repeated the warning twice in the same release: do not approach these individuals or attempt to intervene; contact law enforcement instead. Under California Penal Code section 13665(a)(1), the Sheriff's Office also released a booking photograph of Colegrove and a photograph of Hansen to help the public identify the wanted pair.
The Harwill Court shooting was the second Eureka-area house shooting in three days. In the early morning of October 31, at about 5:50 a.m., deputies were called to the 500 block of Higgins Street, also in Eureka, where a residence and a vehicle had been struck by gunfire in what investigators called a drive-by shooting; nobody was injured there either. A white-and-red 2016 Kia Soul, reported stolen from Eureka and believed to have been used in that shooting, was recovered later that day in the 2200 block of McKinleyville Avenue. The Sheriff's Office releases do NOT say the two shootings are connected, and this story does not claim they are — but two homes shot up in the same small area within three days is the context in which Myrtletown residents are now being asked to watch for two wanted teenagers.
The places in this story
Myrtletown is an unincorporated community immediately east of Eureka, the county seat of Humboldt County on California's North Coast — a small residential area of quiet courts and drives off Myrtle Avenue, where Harwill Court and Circle Drive sit. Hoopa, Colegrove's home community, is an inland Humboldt County community to the northeast, and McKinleyville, Hansen's, is the county's large unincorporated community to the north. All three places are within the same county sheriff's jurisdiction, which is why one office — and one Major Crimes Division — is running the whole case.
What happens next
The immediate next step is the search: as of the November 4 release, both suspects were wanted, not in custody, and the Sheriff's Office was asking the public for sightings and tips rather than announcing arrests. If Colegrove and Hansen are arrested, they would be booked into the Humboldt County jail and brought before a judge in Humboldt County Superior Court, where the warrant charges would be read and bail addressed; the conspiracy and criminal-threats counts suggest prosecutors would also have to lay out what the pair are alleged to have planned and said, evidence that has not been made public so far. The Sheriff's Office said additional information would be released as it becomes available. Awaaz Punjab will update this story if arrests are made.
