Victims of a local cancer doctor were bused into Detroit federal court to face the man who gave their family members treatment they didn't need - for cancers that they didn't have.
Sentencing could last all week for Dr. Farid Fata because so many victims want to confront him.
Victims tell FOX 2 the anger they feel is not only for what Fata did, but for his attitude now - saying he has no remorse.
"At night he would sit there and think how he could help somebody else and now he's gone," said Patricia Loewen, whose father died in Fata's care. "I even had to borrow money to bury him because we spent all our money trying to get m husband back healthy. And Fata could care less."
Loewen's story - like so many others.
"There's people who can't come forward," said Loewen. "Those of us who have a voice, are speaking out as an army of one."
That army of one stepped off a charter bus and into federal court Monday. The cancer doctor admits to committing fraud against insurance companies and misdiagnosing hundreds of patients - $34 million worth.
How can somebody do that knowingly when they're hurting somebody," said one woman. "And continuing to do that just for money."
Minister Michael Hester who lost his wife to Fata, called it "nothing less than genocide."
"I think he treated certain people properly," said Hester. "And other people - because of race, creed, color or beliefs, he didn't care about them."
Many families left behind, call Fata a monster and a murderer.
On Monday a judge hearing from Dr. Dan Longo, testifying on the amount of medication given to patients - that in some cases 6-8 doses were necessary.
But, it's now been proven that in some of those cases, patients treated by Fata 60-90 doses were given. Many believe Fata only stopped because he got caught.
Many families thank Angela Swantek. She says she interviewed to work with Fata and shadowed a nurse but stayed for an hour and a half before she ran out of the office.
"I saw not only were the drugs being given incorrectly, but I had an idea what his motivation was," said Swantek, who reported her findings to the state.
While Fata is asking for a sentence no more than 25 years, prosecutors are seeking a 175-year prison sentence. Anout 150 victim impact statements have been filed as these families ask for Fata to get life in prison.
