Shawn Walter Bair charged into Martin's Supermarket in Elkhart around 10 p.m. and fatally shot a female customer, 44, and a store employee, 20, reported Sgt. Trent Smith.

"I wouldn't say it was well-planned, but it was obviously thought out," explained the official. "He was going to the store with a mission."

The store employee was identified by a friend on Facebook as Krystle Dikes. Authorities had not released the identities of the victims before notifying family members and relatives.

Bair's manic attack was put to a stop by two police officers who quickly arrived on the scene and fatally shot the 22-year-old just as he pointed his 40-caliber handgun at a possible third victim.

Authorities have not determined the shooter's motive, but Bair's Facebook account allowed investigators a look into his demented mind.

Before the Indiana supermarket shooting, Bair expressed a fascination with serial killers and uploaded a gruesome image of himself with his face bloodied by what he said was a bite from a pit bull.

"I MAY BE GOING TO HELL BUT ATLEAST I'M GOING HONEST AND YOU KNOW WHAT THATS ALL I'VE EVER BEEN YOU LOOK AT ME AND SEE THIS FREAK I SEE A GOD BECAUSE I EMBRACE MY F----- UP SIDE AND WHEN I'M IN HELL I HOPE YOU PASS THROUGH MY RACK HAVE FUN WITH THAT AHAHAHAHAHAHAHA," Bair posted on his Facebook page on August 2011.

Another post by Bair that same month was equally demented.

"I HOPE YOU ALL BURN IN THE FURTHEST PITS OF HELL I HOPE THE TORTURE LASTS FOREVER AND EVERY SECOND OF EVERY MINUTE YOUR THINKING ABOUT YOUR LOVED ONES. EVERYONE WILL PASS THROUGH TORTURE RACKS MADE OF BONE WITH RAZOR BLADES MADE FROM FIRE I WILL BE PICASSO WITH A FIRE RAZOR BLADE BENEATH MY FINGERS," the shooter wrote.

Other posts contained strange artwork of clowns, crime scenes and an image of notorious murderers such as Jeffrey Dahmer and Ten Bundy.

Officials had not yet released the identities of the victims in the Indiana supermarket shooting, 

"There's not a day that goes by, it seems like anymore, where we're not learning of a school shooting or at a business. ... We hope that this would never come to our hometown and here it is," Smith told reporters in a press conference at the scene of the crime.
