The Portland Police Bureau just released another update on last night's officer-involved shooting, saying it still isn't clear whether the man who was wounded—identified as 31-year-old Alberto Flores-Haro—even fired at officers before he was shot.

That's a revision from comments given just after the shooting about gunfire being "exchanged." Detectives have found a handgun and are still looking for shell casings, according to the bureau's statement. Three officers from Washington County's tactical negotiations team were "involved directly": one officer from Hillsboro and two county sheriff's deputies.

The bureau also says that the Multnomah County District Attorney's Office is investigating alongside Portland's homicide detectives. So far, though, neither the officers involved in the shooting nor Flores-Haro have been interviewed. But witnesses who have been interviewed are telling detectives that "prior to the shooting, the officers repeatedly identified themselves as law enforcement officers."

"The city takes incidents such as this very seriously. As with any officer-involved shooting, there will be a thorough investigation and we will make sure every element is examined," Mayor Sam Adams was quoted as saying in the bureau's statement.

As noted in my last post, on the Oregonian's report that Flores-Haro had gone outside with a gun to confront someone he though was a prowler, getting to the bottom of this will be sticky. Out-of-town officers are governed by their home agencies' union contracts and discipline policies—and current intergovernmental agreements don't explicitly give Portland investigators the right to compel their testimony.

Read the entire update after the cut.

Portland Police Bureau Detectives and the Multnomah County District Attorneys Office are conducting the investigation into the March 13, 2012, shooting involving the Washington County Sheriff's Office Tactical Team (TNT). TNT was assisting Portland Police Gang Enforcement Team Detectives by serving a high-risk search warrant related to a robbery and shooting that occurred on Sunday March 11, 2012. Portland's Special Emergency Reaction Team (SERT) is out of town training and TNT is the primary back-up agency for SERT.

"The City takes incidents such as this very seriously. As with any officer-involved shooting, there will be a thorough investigation and we will make sure every element is examined," said Mayor Sam Adams.

The shooting, which occurred at approximately 10 p.m. in the 9500 block of Woolsey Avenue, was not related to the search warrant. TNT members were approaching the search warrant location when they were confronted by a male subject armed with a handgun near his front door. Three members of the Tactical Negotiations Team, which is a multi-agency team, were involved directly in the shooting: one officer from the Hillsboro Police Department and two officers from the Washington County Sheriff's Office. The man who has been identified as 31-year-old Alberto Flores-Haro was wounded and transferred to an area hospital, where he is in serious condition.

Preliminary information released at the scene was that an exchange of gunfire occurred. However, Detectives have been searching for shell casings at the scene, which is lined by a heavily wood area. A handgun was recovered at the scene, but detectives have not determined if the man shot at police. The investigation has revealed that prior to the shooting, the officers repeatedly identified themselves as law enforcement officers.

Detectives will continue processing and canvassing the scene and are conducting interviews, including witness officers. The wounded man and the officers involved have not been interviewed; therefore, no additional information can be released at this time.

Following the shooting, members of TNT secured the location and then continued to the original location to serve the search warrant in connection with Sunday's shooting. This shooting occurred at approximately 11:17 p.m., outside a residence in the 9600 block of North Woolsey Avenue. The victim, 20-year-old Jose Monroy, was shot during an apparent robbery.

Gang Enforcement Team detectives immediately began investigating Sunday's shooting and developed information resulting in arrest warrants for the two suspects: 20-year-old Anthony Bagsby and 16-year-old Cocoa Taplin. The detectives obtained a search warrant for a residence in the 9500 block of North Woolsey Avenue.

Taplin was taken into custody by officers in the neighborhood near the residence. Bagsby was located by TNT at the residence and taken into custody. A subsequent search of the residence located a handgun investigators believe was used during Sunday's robbery and shooting.

Bagsby was booked into the Multnomah County Jail for Attempted Murder, Assault in the First Degree and Robbery in the First Degree.

Taplin was booked into the Donald E. Long Juvenile Detention Home for Attempted Murder, Assault in the First Degree and Robbery in the First Degree.
