DeKALB | Mid-morning on Monday, the final two of four suspects charged in the death of Luis Noriega were arrested after they turned themselves in at the DeKalb police station.

Nathan Schrank, 22, an NIU marketing major from Lockport, was arrested at the scene on April 15. The warrants for three other suspects were announced Friday.

Fred Jakob, 22, an operations and information management major from Lockport, Christopher Tadder, 22, an operations and information management major from Lockport and Emily Hobbs, 21, a political science major from Plainfield, were all wanted on four counts of aggravated battery.

Hobbs turned herself in on Saturday at approximately 2:30 p.m. and was released after posting 10 percent of her $50,000 bond.

Tadder and Jakob were booked and released Monday after they posted bond, between 8:30 and 10:45 a.m. Tadder and Jakob each posted $10,000, or 10 percent of their $100,000 bonds.

Schrank is charged with two counts of first-degree murder, one count of involuntary manslaughter and three additional counts of aggravated battery. Schrank is currently being held at the DeKalb County Sheriff’s Office and his bond is set at $500,000.

Sociology instructor Christine Janis defined these charges generally, not specifically, for this case.

Aggravated battery is physically harming someone, inflicting serious wounds and/or using a weapon, Janis said. Involuntary manslaughter is recklessly disregarding a risk. First-degree murder is premeditated, intentional and malicious, meaning it was planned ahead of time and the suspect knew the damage that would be done, she said.

Aggravated battery and involuntary manslaughter are Class 3 felonies and a person found guilty can be sentenced to no prison time, but if sentenced, can be face up to five years in prison. First-degree murder is punishable by a term in prison of between 20 and 60 years, according to a press release issued by the DeKalb County state’s attorney’s office.
