Multiple knives were some of the items seized by Chapel Hill Police after two bodies were found in a home last October, according to a report from WRAL-TV.
The Raleigh television station is citing a new search warrant.
Authorities previously said they believed 53-year-old Eric Dana Gibson murdered his 86-year-old mother Margaret Montgomery Gibson at a home on the corner of Deming Road and Franklin Street on October 12.
The two bodies were found by a realtor. The home had been listed for sale.
The realtor told 911 operators that she saw “blood everywhere.”
WRAL’s Friday report also said police seized two laptop computers among linens and other items taken from the home.
