Evansville Police believe robbery was the motive in the death of 33-year-old Nicholas Mathew.
Mathew's body was found on Christmas Eve at his apartment in the 1100 block of Hatfield Drive.
Police went to check on Mathew after receiving a call from concerned family members.
Mathews suffered multiple stab wounds. His death is being treated as a homicide. An autopsy is scheduled for tomorrow.
During the death investigation, police were monitoring a call where a cab driver and passenger were stabbed during and armed robbery in Vanderburgh County.
Investigators say they received information shortly after that robbery that they believed might connect the two cases.
After a joint response between the Vanderburgh County Sheriff's Office and EPD, 24-year-old John Vernon Jackson, Jr. was arrested near the robbery scene.
Police say items were found in the cab that connected Jackson to Mathew, including his credit cards.
Detectives say Jackson admitted to robbing and stabbing the cab driver and passenger. In addition, he admitted to cutting a clerk during a gas station robbery on December 20 at 715 N. Weinbach.
They say Jackson also admitted to being at Mathew's apartment and robbing the victim, but denied being involved in his death.
Police say Jackson is the only suspect identified in the case.
Jackson is in custody for the robbery and stabbing of the cab driver. Click here for more details on that incident.
The murder investigation is ongoing. Police are still trying to determine if anyone else was involved in Mathews' death.
