KALIHI, Hawaii -- Dozens of Hawaii residents who escaped the collapse of their makeshift apartment building Sunday night said the landlord subjected them to medical experiments on top of unsafe living conditions.

Residents of the partially-collapsed apartment building said after landlord Daniel Cunningham accumulated thousands in building fines, the building was facing foreclosure. They told TV station KITV that his building was in terrible disrepair and was dangerously overcrowded.

"It's not right. The way it exists, it's not safe. It should be down. There are way too many people," neighbor Jay Young said.

The building tumbled into a nearby stream Sunday, but it was what former residents said afterward that raised terrifying questions.

Residents said they were human guinea pigs for Cunningham's medical experiments.

Former tenant Richard Sumiye had to be helped to shelter. He told KITV that Cunningham blinded him after he used a needle to inject a solution around his eyes.

"So I got blind because of Daniel Cunningham -- because of what he did to me," Sumiye said.

Former tenant Jesse Taylor said he and others accepted the injections because they feared eviction.

"We were in pain. We were desperate and he took advantage of that," Taylor said.

Cunningham lost his chiropractor's license in 1996 for injecting patients. He recently claimed to have invented a stem cell treatment to extend life indefinitely.
