Arthur Ream, a 68-year-old convicted pedophile and the prime suspect in the search for Kimberly King, is considered a person of interest in the disappearances of several girls in MI.
Though Dwyer said investigators believe four to six girls may be buried in the Macomb County field, he provided CNN with the names of only four of them.
King's sister, Konnie Beyma, spoke at the press conference, saying she has hope her sister's remains will be found and that the developments in the case bring hope to the families of other missing girls as well.
Ream was convicted of first-degree murder in her slaying and sentenced to life in prison.
William Dwyer, police commissioner for the town of Warren, said no remains have been discovered yet but "what we have found makes us cautiously optimistic we're on the right track". Police previously said the search could take between two and four days. Dwyer did clarify, though, that Ream is not the suspected Oakland County Child killer, because he was in prison from 1974-1978.
"You want to be a man about it?" the police commissioner said in an appeal to Ream.
Almost three dozen law officers and Federal Bureau of Investigation agents are searching the site, Warren Mayor Jim Fouts said.
When asked about the search for bodies, Police Commissioner Dwyer did have the following to say.More news: Midterm matchups set after Republican primary races in 4 states

Authorities work in a rural wooded area in southeastern MI, searching for the remains of a 12-year-old girl last seen in 1979.
On Monday, officials and searchers cleared trees and had 20 people working backhoes. She was last seen in 1979.
Authorities say they have little doubt Ream is responsible for the murders of up to seven girls.
Investigators were hoping Ream would cooperate more than he has, Dwyer said.
Ream, who turned 69 on Wednesday, was sentenced in 1998 to 15 years in prison for criminal sexual conduct and taking indecent liberties with a child less than two years earlier. Detectives say that Ream tricked Zarzycki into entering his vehicle by promising to take her to a surprise party for his son. 15-year-old Kim Larrow never returned to her Canton Township home and was declared a missing person in 1981.
Just like in that video, where detectives got Ream to share details of where Cindy Zarcycki was buried, police revealed to us it was through Ream's bragging in prison and a failed lie detector that led them to look for more victims. Beyma says that she no longer believes that her sister is alive. Zarzycki had been dating Ream's son at the time of her disappearance. She was last seen in 1986 after being lured to a Dairy Queen in Eastpointe, just north of Detroit.
"We also believe that there's maybe four to six other girls that have been reported missing that are buried there", he said.
