Hillsborough Police are asking for public assistance on three unsolved crimes.

Jeffrey Duke was 30 years old when he was shot and killed on Homemont Avenue in Hillsborough in November 2005, but officers are still looking for his killer. Authorities say investigators have identified a person of interest in the case and they are looking for additional information to help lead to an arrest.

Police do believe that information about the murder “has been shared with people in the community,” according to a release.

A second homicide investigation is ongoing from a 2007 shooting early in the morning of January 7, when 21-year-old Jaquienton Sellars was found in his home on Hayes Street. Police say he was bleeding on the floor when officers arrived and later died at Duke University Hospital.

Authorities say it appears Sellars was shot during a home-invasion robbery. Sellars exchanged gunfire with the intruders, police say. Sellars’ girlfriend was in the home at the time but was uninjured.

The third unsolved crime Hillsborough Police are asking for information about is an arson when a bottle containing flammable material was thrown through a window at the Orange County Republican Party headquarters in the Shops at Daniel Boone complex.

Graffiti was also spray painted on the side of an adjacent building.

The crime is being investigated by authorities from the local, state and federal level, but there have been few updates.

Anyone with information regarding the two homicides is asked to contact Sergeant Chip White at (919) 296-9532 or by e-mail. Individuals can also submit information regarding the arson to Investigator Jon Purvis at (919) 296-9533 or by e-mail. The state Republican Party is offering a $5,000 reward for information that leads to an arrest and conviction in the arson case.

Anonymous tips can also be submitted through the town’s website or by calling (919) 732-3975.
