The man who engaged in a 12-hour standoff with law enforcement last night before shooting and killing himself this morning has been identified as Greg Allen Hawkins, 48, of Peoria, Ariz. The standoff took place at Hawkins' mother's home on the 1800 block of Mesa Ave., located on the hill above the Tip Top Club south of Eureka.

Hawkins' mother escaped from the home shortly after the standoff began. An ailing man was later rescued from the home by law enforcement, according to a release from the Humboldt County Sheriff's Office.

Hawkins had been missing for two weeks and was considered a "person of interest" in the Dec. 21 murder of Cynthia Langrall in Glendale, Ariz. Hawkins' roommate, 55-year-old James Keefer, has been missing since Dec. 13. Keefer's car, a white 2005 Chrysler Sebring, was found with Hawkins at the scene of the standoff.

Hawkins was reportedly in communication with law enforcement negotiators throughout the night and into the morning. He shot himself around 9:20 a.m., according to the release. Detectives with the Glendale Police Department are scheduled to travel to Humboldt County today to continue their investigation.
