A 66-year-old Detroit man was formally charged after he shot and killed two women in a senior citizen home he was living in on Sunday, SeattlePi.com reported.

Mike Reda was arraigned on Wednesday for two counts first-degree murder in addition to other felonies in a Detroit courtroom.

On Sunday evening, he killed Deborah Socia, 59, and Maria Gonzalez, 61, at Pablo Davis Elder Living Center after allegedly blaming them for a breakup with his ex-girlfriend.

He plead not guilty and was ordered to be held without bond. Reda does not have a lawyer.

After Reda and his girlfriend got in an argument, he retrieved a rifle from his apartment and attacked Socia and Gonzalez, claiming they were the reason behind the breakup, officials said.

Socia was pronounced dead on arrival at Henry Ford Hospital and Gonzalez was pronounced dead at the scene. 

A preliminary examination of the case is scheduled for Oct. 31.

Detroit Police spokeswoman Kelly Miner said Reda surrendered and was immediately detained by police. The senior center, which has around 80 housing units, was evacuated and residents were placed on a police bus.

"I didn't see the rifle until he got right on top of us," witness Paul Fratangelo told The Detroit News. "I said 'Oh, my God ...' He said 'Get on the ground and start praying.'

"It was the grace of God that he didn't shoot me. I really thought he was going to shoot me. I thought it was over. Instead, he shot both my friends."

Will Staples, another resident at the center, said he came back from a Lions game to find the entire complex barricaded by police.

"Everyone knows everyone in here, but they were all good friends," Staples said. "People called them the Three Musketeers," he said while talking about the two victims and Reda's ex-girlfriend.

Authorities said the ex-girlfriend was never one of the his targets.
