An Indiana teen who had an “obsession” with the school shooter who murdered 17 people exactly seven years ago is accused of plotting another Valentine’s Day massacre, authorities say.

Two juveniles were detained for fleeing from cops during an attempted traffic stop in Hartselle early Friday morning, according to the Morgan County Sheriff’s Office.

An Independence police officer shot and killed a suspect after that suspect opened fire Thursday night. The Eastern Jackson County Police-Involved Incident Team says this encounter began at 9:45 p.m.

A detective said they interviewed Shockley Wednesday and learned she had been planning the shooting for at least a year.
