LAFAYETTE, Ind. (WLFI) — Andrew Alcorns, a man previously named a "person of interest" in a Lafayette killing and arson, has been charged in relation to the alleged crimes.

Prosecutors filed murder, attempted murder, aggravated battery and arson charges against Alcorns Thursday. 

Court documents say Alcorns broke into Ronald Whiles' South 31st Street home on April 7. Prosecutors said he then robbed Whiles, shot him to death several times, stabbed his roommate, set fire to the home and then ran away. 

Firefighters said when they arrived, Whiles' pockets were turned out, his wallet found on the bed with items removed and dresser drawers were open. Officers said spent shell casings were also found inside. Lafayette fire investigators also noted irregular burn patterns in the living room. 

Whiles' roommate, Thomas Day, was initially listed as critical, but his condition improved. He shared his survival story with News 18 in the weeks after the crime. Day was stabbed 29 times and spent three weeks in the hospital.

Officers found several break-ins to vehicles in front of the home that morning, according to prosecutors. Guns were stolen from neighbor's vehicles, and one would later be identified as the weapon used to kill Whiles, according to court documents. 

Three days after the crimes, investigators spoke to a woman who said Alcorns was married to her sister. She said her sister had died on April 4, three days before the killing and arson. The woman said she believed Alcorns may have been involved in Whiles' murder because he had said he would "rob people until he had the money to post his girlfriend's bond." She claimed Alcorns said he needed to "hit a lick" at Whiles' house because Whiles always had cash.

Alcorns' girlfriend, Paige Millikan, was arrested on April 1 in Madision County after a traffic stop. Alcorns was also in the car and ran from officers, according to court documents. Police in Madison County issued a warrant for Alcorns' arrest. He pleaded guilty there this week to Carrying a Handgun without a License, Possession of Altered Handgun and Resisting Law Enforcement.

Alcorns has been in the Tippecanoe County Jail since Monday, awaiting a paternity hearing. 

On April 11, Lafayette investigators were called to Dayton, Ohio where Alcorns led officers on a 9-hour standoff. He eventually was taken into custody after he shot himself in the head. Alcorns survived the self-inflicted shooting.

Millikan told police she called Alcorns while she was in jail and told him to get bond money from Whiles. She knew Whiles would have rent money that day before he could go to the bank. According to court documents, she said Whiles liked her and would help out. 

Police later spoke to another man who knew Alcorns. He said Alcorns showed up at his home on April 6, a few days after his wife died and a day before the crimes. He said Alcorns seemed to be "losing it" and that Alcorns said he wanted to kill someone. 

According to prosecutors, Alcorns' DNA evidence was found on the weapon used to kill Whiles.
