Brice Holliman disappeared on April 9, 2015.

And with the one-year anniversary coming up on Saturday, local law enforcement agencies are still working to find out exactly what happened.

The Orange County Sheriff’s Office announced on April 15 of last year that the 41-year-old Holliman had been reported missing after he was last seen on April 9.

Authorities say he left a friend’s home on Saxapahaw-Bethlehem Church Road near the Orange – Alamance County line around 6:30 in the evening and was last seen driving away in a white Lexus ES300. He reportedly told his friends that he would be back in about 30 minutes but never returned.

Holliman’s vehicle was found about one month after he went missing.

His family members have been calling for anyone with information to come forward and tell law enforcement.

Records show the majority of the action in the case has taken place in Alamance County and authorities have questioned multiple individuals on several occasions throughout the investigation. Documents also show that law enforcement agencies are investigating this case as a homicide.

Search warrants were taken out in March of this year to look for Holliman’s remains on a property off of Mineral Springs Road in Alamance County.

Orange County Sheriff Charles Blackwood says no remains were found as authorities investigated open wells on the property. But he said he feels that authorities are very close to finding a resolution to this case

“We are absolutely certain that one or more people know exactly what happened in this case,” Blackwood says. “And time will allow, we feel, at least one of these persons to either get mad at the other or to get angry with the other or somehow be motivated to come forth and tell the truth.

“And we look forward to the day that that happens, and we feel that it might happen sooner than later.”

Blackwood says his office is working with neighboring agencies in addition to authorities outside of the state, including but not limited to the state of Georgia.
