Police are working to uncover what happened when a man fatally shot someone, then injured a police officer before killing himself. New surveillance video shows the moment the incident began.
The gunman who allegedly shot a police officer and another man who was found dead in an SUV nearby following an hours-long standoff with police Thursday night in Brockton, Massachusetts, has been identified.
The gunman has been identified as Kevin Serpa, 32, of 62 Taber Avenue in Brockton, the Plymouth District Attorney's Office said Friday morning.

Officials said Serpa shot a Brockton police officer four times from the second floor of his home. The officer was taken to Boston Medical Center with non-life-threatening injuries and was released Friday morning.

The officer was later identified as Robert Otis, a recent police academy graduate.
The incident began around 5:45 p.m. Thursday when Brockton police received several 911 calls about a man with a gun, officials said.
After shooting the officer, Serpa was holed up inside his residence for several hours, during which he was negotiating with police, the district attorney's office said.
In surveillance footage, an SUV is seen driving down Tabor Avenue and parking, before someone walks up it and fires. The vehicle lurches forward, and the gunman follows it, firing again into it. A police SUV arrives at the scene, but gunshots are fired -- from a second-floor window, according to prosecutors.
Around 9:30 p.m., officials said he exited the house and shot himself outside. He was taken to Good Samaritan Medical Center in Brockton, where he was pronounced dead shortly after 10 p.m.
Authorities said they also found a male gunshot victim dead inside a silver SUV not far from Serpa's home. That man has been identified as Christopher Gomes, 28, of Brockton.
It was not immediately clear whether the death and the situation with the gunman were connected.
Massachusetts State Police and Brockton police continue to interview witnesses and review video surveillance as part of their ongoing investigation.
The district attorney's office said the incident does not appear to be an act of random violence.
