Additional evidence connected to MacKenzie Lueck's disappearance and murder was discovered near the Jordan River Parkway Monday.
According to police, a city park employee reported the suspected items.
Police have been looking for evidence for more than three hours near 700 N. Redwood Road.
Two divers found items that were later booked into evidence in the river.
The Salt Lake City Police Department did not say what they found.
Police say Ajayi was the last person Lueck saw at Hatch Park in North Salt Lake before she disappeared in the early hours of June 17. The pair had been communicating on Sunday and the day Lueck went missing.
Police have not discussed how the pair knew each other or motive.
On June 26, police found Lueck's DNA in Ajayi's backyard in Salt Lake. They also found some of her personal belongings in an alleyway adjacent to the home.
Neighbors told police Ajayi had been burning things on Monday, June 17 and it smelled "horrible," court documents state. The fire was located behind Ajayi's garage--the same place detectives found the freshly dug site with Lueck's belongings and DNA.
Her charred body was discovered a week later in Logan Canyon.
