Both teenagers wanted over the shooting that struck a house in Myrtletown, near Eureka, are now in jail. The Humboldt County Sheriff's Office said 19-year-old Alyssa Hansen turned herself in to deputies at about 5:31 p.m. on Friday, November 6, and 19-year-old Tyler Colegrove turned himself in later the same evening, at about 10:31 p.m. Both were booked into the Humboldt County Correctional Facility on the arrest warrants issued in the case, the Sheriff's Office said in a press release published on Saturday, November 7.
The surrenders are the newest development in a case this newsroom has followed since the warrants were issued. On November 4, deputies publicly identified Colegrove and Hansen as the suspects in the November 3 shooting on Harwill Court and announced that arrest warrants had been issued for both. Friday's bookings mean the two are in custody roughly three days after the shooting and two days after they were named.
The night a Myrtletown house was shot up
The case began in the early hours of Tuesday, November 3. At about 2:36 a.m., the Sheriff's Office Emergency Communications Center received multiple 911 calls reporting gunfire in the Circle Drive area of Eureka, according to the Sheriff's Office. Deputies who responded found a residence on Harwill Court, in the Myrtletown area just east of Eureka, that had been struck by gunfire. No injuries were reported. The Sheriff's Office Major Crimes Division took over the investigation, and deputies said preliminary information indicated the shooting was targeted — not random.
It was the second shooting in the Eureka area in three days. On October 31, a car was shot multiple times on Higgins Street in Eureka and was later connected to a stolen Kia, the Sheriff's Office said at the time. No arrests had been made in either shooting when the Harwill Court warrants were announced, and investigators asked the public for help in both cases.
The warrants: attempted murder, criminal threats and conspiracy
In its November 4 announcement, the Sheriff's Office identified the suspects as Tyler Peter Colegrove, 19, of Hoopa, and Alyssa Regina Hansen, 19, of McKinleyville — two communities in Humboldt County, on California's North Coast. Colegrove was wanted on charges of attempted murder (Penal Code sections 664/187), criminal threats (Penal Code section 422(a)) and conspiracy to commit a crime (Penal Code section 182). Hansen was wanted on a charge of conspiracy to commit a crime (Penal Code section 182). These are allegations set out in arrest warrants; neither suspect has been convicted of anything in this case, and both are presumed innocent unless the charges are proven in court.
Two surrenders, five hours apart
The Sheriff's Office gave a short, precise account of Friday evening. Hansen, described as wanted in connection with the November 3 shooting on Harwill Court, presented herself to deputies at the Sheriff's Office at approximately 5:31 p.m. Colegrove did the same at approximately 10:31 p.m. Deputies booked both into the Humboldt County Correctional Facility on the warrants connected to the investigation. The release did not say whether either suspect made any statement, and it announced no new charges beyond the warrants themselves.
Under the California Penal Code sections listed by the Sheriff's Office, sections 664/187 cover an attempt to commit murder; section 422(a) covers criminal threats — threatening to commit a crime that would result in death or great bodily injury; and section 182 covers conspiracy, an agreement between two or more people to commit a crime. A warrant records what prosecutors and investigators allege; guilt or innocence is decided later, in court.
A separate Eureka shooting — police say it is not connected
The arrests land in a week of gunfire around Eureka. On Thursday, November 5, at about 8:40 p.m., Eureka police officers responded to a shooting in the 1200 block of G Street and arrested Dustarta Riggs, 42, of Eureka, for attempted homicide, according to the Eureka Police Department. That department stated plainly that the G Street incident does not appear to be connected to the recent shootings in the Arcata, Pine Hill or Myrtletown areas — a distinction residents have been asking about as the cases stacked up within days of each other.
What happens next
With both suspects booked, the case moves to the Humboldt County District Attorney's office, which decides the formal charges, and then to arraignment in Humboldt County Superior Court, where the two will hear the charges against them and enter pleas. The Sheriff's Office says the Harwill Court investigation remains active, and it is still asking anyone with information about the case or related criminal activity to call the Sheriff's Office at (707) 445-7251 or the Sheriff's Office Crime Tip line at (707) 268-2539. Awaaz Punjab will report the court outcome when it is known.
