The California Department of Justice has launched an investigation into a fatal shooting incident involving a California Highway Patrol officer and a pedestrian on Interstate 105 in south Los Angeles County. The incident, which was captured on a video posted online, has raised concerns about the use of deadly force by law enforcement.

According to a news release from the California Highway Patrol, officers responded to a call on Sunday afternoon about a person walking within traffic lanes on the westbound side of the freeway. Upon making contact with the pedestrian, a struggle ensued, leading to an officer-involved shooting.

In a separate statement, the California Highway Patrol revealed that the officer involved in the incident had felt "in fear for his safety" after the pedestrian allegedly used a taser against the officer during the struggle. In response, the officer discharged their service weapon multiple times, fatally shooting the pedestrian.

The initial statement made by the highway patrol did not mention the use of a taser, but the agency has yet to provide an updated statement regarding this detail. CNN has reached out to the California Highway Patrol for clarification.

The exact circumstances that led to the altercation remain unclear, and the identity of the pedestrian has not been disclosed pending notification of next of kin, according to the Los Angeles County medical examiner's office.

Under California law, state prosecutors are required to investigate incidents involving police shootings resulting in the death of an unarmed civilian. The California Department of Justice has taken charge of the investigation and has been asked to furnish further details regarding the incident.

The bystander video, which circulated on social media, shows the officer and pedestrian engaged in a struggle on the freeway. The officer is seen drawing their gun and firing shots, both near the pedestrian and while backing away.

The investigation will look into the alleged use of a taser against the officer and whether it constituted a justified use of deadly force. The California Department of Justice has been contacted by CNN to confirm if they are aware of the bystander video and its significance in the case.

As questions continue to arise surrounding this tragic event, the California Department of Justice's investigation aims to provide clarity and ensure accountability for the actions of both the officer and the pedestrian involved.
