Pittsburg Police Announce Arrest in 20 Year Old Cold Case

On Thursday, the Pittsburg Police Department announce an arrest in a Sept. 27, 2020 homicide.

It was September 27th, 2000, when Pittsburg Police Officers received a call about a man who had been shot while sitting in his car at 1605 Railroad Avenue. The victim was 22-year-old Danny Guyse of Pittsburg. Sadly, after he arrived at the hospital, Mr. Guyse died of his injuries.

Pittsburg Police Detectives had very little to work with in building a homicide case. There were no viable leads at the time. The only worthwhile information was that the person responsible possibly fled the scene in a light colored Ford Mustang.

As with all homicide investigations, detectives continually worked the case over the following year. Ultimately, the investigation was assigned to the department’s Cold Case Unit in a continued effort to determine Mr. Guyse’s killer.

Over the next two decades, numerous suspects and persons of interest were developed and investigated.

In 2019 detectives got a break in this case and identified 44-year-old Paea Tasini as possibly involved in this homicide. As a result of the newly learned information, detectives authored a search warrant; where detectives obtained additional information critical to the case.

Based on the newly obtained information and continued work by detectives, this case was taken to the Contra Costa County District Attorney’s Office for review. On February 17, 2021, the District Attorney’s Office filed a criminal complaint; charging Paea Tasini for the murder of Danny Guyse. Tasini was additionally charged with another count of attempt murder related to a separate shooting that also occurred in 2000. Late Wednesday evening, with the assistance of the Elk Grove Police Department, detectives located Tasini at his residence in the city of Elk Grove and placed him under arrest.

Tasini is currently being held at the Martinez Detention Facility on a ten million dollar bail.
