A South Dakota native was charged with first degree murder Tuesday in connection with a fatal shooting in Omaha. 19-year-old Kyle Bormann is accused of shooting a young woman while she was waiting in line at an Omaha fast food restaurant.

Omaha officials say they still don't know what Bormann was thinking, or what his motive was Sunday night.

A memorial at the scene of Sunday's shooting remembers a young woman full of life.

"She went to UNO, she wanted to go to nursing school. She was wonderful, loved life," said a friend.  

As family and friends of 21-year-old Brittany Williams mourn, the Douglas County Attorney's office has filed first degree murder charges against Bormann and released details about the shooting.

Douglas County Attorney Don Kleine says Bormann was at least 100 feet from the restaurant when he allegedly used a Winchester rifle to take the life of Brittany Williams with a single shot to the head. Kleine said the gun was a Winchester 670a .243 caliber bolt action rifle with a scope, and belongs to Bormann.

"Apparently he had some history of hunting lived in South Dakota. That's where he was from, and was a hunter," stated Douglas County Attorney Don Kleine.  

When he was arrested on Sunday night, police said they found Bormann dressed as a hunter.

"He was dressed in camouflage gear, camouflage jacket, camouflage pants," said Kleine.  

Kleine says the shooting still appears to be completely random.

The Omaha Police Department confirmed Bormann is in jail and will make his initial court appearance Wednesday morning in Omaha.
