The identities of two sisters found murdered in a Billings apartment on Sunday have yet to be released.
Meanwhile, Andrew Scott Denning, 20, the suspect in the slayings, is expected to make his initial court apperance in Justice Court on Wednesday afternoon. He's being held in the Yellowstone County Detention Facility.
Police Lt. Kevin Iffland said he met with the Yellowstone County Attorney's Office on Tuesday morning, and is still unable to disclose the identities of the victims, ages 21 and 22, or how they were killed.
"We are waiting for the OK from the County Attorney's Office," Iffland said.
County Attorney Scott Twito said representatives of his office are meeting with the victim's family on Tuesday afternoon, and that the names of the victims will be released "once we meet with members of the family and explain the situation to them."
The women, described as sisters by close friends, were found in apartment 113 of the Ponderosa Acres "O" complex at 1301 Industrial Ave. on Sunday morning.
A concerned co-worker of one of the victims called the police that morning and reported that the victim had not shown up for work or answered phone calls.
The women's bodies were discovered at around 11 a.m. on Sunday. By 2 a.m. on Monday, police had arrested Denning, of Billings. He is accused of two counts of deliberate homicide.
Friends say Denning, a 2009 Billings West High School graduate, knew the victims and had partied with them.
