Authorities in Kentucky say a teenager accused of fatally shooting two high school classmates and wounding several others showed no remorse when talking about the carnage.
Police say Gabriel Ross Parker seemed to view his actions as a science experiment.
Parker has been charged as an adult in the January 23 shooting at Marshall County High School in western Kentucky. Media reports this week cite court documents and videos released after the case was moved to adult court. Parker turned 16 after the shooting.
Marshall County Sheriff's Captain Matt Hilbrecht testified that Parker told police he was interested in science and wanted to see how people would react.
"He said he wanted to see how students would respond, how police would respond, how society at large would respond to it," said Hilbrecht.
