YouTube shooting: Police questioned attacker hours before incident, found her harmless
The police chief added that the suspect had a registered semi-automatic handgun, which was found at the incident scene.
A few hours before Nasim Aghdam opened fire on YouTube headquarters in San Bruno, California on Tuesday, police officers reportedly questioned the suspect in her car, according to the Associated Press. The deadly shooting resulted in three people getting critically injured while Aghdam killed herself before officers could nab her.
Reports state that during the 20-minute questioning by the police officers, Aghdam explained that she was sleeping in her vehicle because she had left home and was facing family troubles. Aghdam, however, never brought up her rage against YouTube, nor did she indicate that she was a threat, AP reported.
The Bureau of Alcohol, Tobacco, Firearms and Explosives spokesperson Ginger Colbrun on Wednesday said that multiple locations around the San Diego area linked with Aghdam were combed, including the homes where she had previously lived. Several vehicles were also searched in the process, according to NPR.
"Agents also completed an urgent trace on the firearm used in the shooting to determine who purchased the gun and where," Colbrun said.
The suspect's aunt, a 39-year-old woman, said that Aghdam had no history of mental illness and was a "really good person," AP reported.
The San Bruno Police Department, earlier on Wednesday, said that Aghdam had "absolutely no link or relationship" with anyone on the scene of the shooting.
The officers concluded her motive and said that "she was upset with YouTube."
San Bruno, California, Police Chief Ed Barberini, during a press conference on Wednesday, said: "We've determined that right now, that's the motivation that we've identified. Whether that rises to the level of terrorism hopefully will be determined in the next couple of weeks."
The police chief added that the suspect had a registered semi-automatic handgun, which was found at the incident scene. Officials said that Aghdam, on Tuesday morning, had stopped in at a gun range, reports state.
