The 19-year-old suspect in a murder of three people, including a ten-year-old girl, appeared in court for the first time Thursday night on seven felony charges. 

Three charges each of criminal homicide and conspiracy to commit criminal homicide, as well as one charge of using a firearm without a license, were filed in front of Lawrence County Judge Scott McGrath Thursday afternoon. 

In court, the judge denied 19-year-old Steven Procopio's bail- citing the nature of the crimes. 

At the same time, officials released the criminal complaint with graphic details about the scene and the crime itself, and about the other suspect in the slaying. 

According to the criminal complaint filed in the court system officers found 31-year-old Lawrence Cannon, 31-year-old Nichole Pumphrey, and 10-year-old Amariah Emery dead.

The complaint says police found Cannon and Pumphrey on the couch with apparent gunshot wounds to the head. 

Emery was found lying at the bottom of the stairs. 

The complaint alleges that the body of Pumphrey was found by one of the other children. The child allegedly said that she went to bed around midnight and "while laying in bed she heard two thumps". 

According to the complaint, the child said that she heard her sister Aramiah go downstairs and ask "what's going on down here?". The girl reportedly said that she heard another thump, and then everything else went quiet and she went back to sleep. 

The girl allegedly told officers that she found her mother but thought there "was ketchup all over her". 

That child said she was able to get into her mother's phone and contact a family member, who then called the police. 

The complaint says investigators talked to another child who told them that she and Amariah Emery were coming downstairs after hearing gunshots when "Steven" pointed a gun at them and shot Amariah. 

The young girl then said that he "triggered' on her and she ducked". It is unclear if a shot was actually fired. 

The criminal complaint also makes it clear that the children feared for their lives. 

Lawrence County District Attorney Josh Lamancusa says the children were initially taken with Children and Youth Services, who then separated them before placing them with members of their extended family. 

Nineteen-year-old Steven Procopio was picked up by police late Wednesday.

New Castle Police Cheif Bobby Salem tells 21 News that Procopio knew Pumphrey and her children.

A woman, identified as Jody Hammer, who lives in the same home as Procopio and was described in court as like a mother to him, was also arrested on charges not related to the homicide after police discovered a marijuana-growing operation while searching the home at 258 Canterbury Road.

The criminal complaint says Hammer is facing a felony charge of obstruction of justice after allegedly withholding valuable information from officers relative to the homicide investigation. Investigators also say she helped another person of interest in the investigation in fleeing from the New Castle area.

Investigators say Hammer drove the third person of interest, who was initially interviewed with Procopio and Hammer, to Cleveland.

The criminal complaint says police tried to reinterview a third person but that he had fled toward Michigan. 

According to the complaint, Procopio told officers that this other male was sitting on the couch with Cannon and Pumphrey when he pulled a gun out of his waistband and began firing shots. 

New Castle Police Chief Robert Salem has told 21 News that they are still looking for the third person of interest.

One thing that remains unclear is the motive for the crime. 

Lamancusa told 21 News, "At the scene there was money, laying on the table, it was in plain view, it does not appear that the motive was a robbery. It does not appear that there was any kind of drug involvement. These individuals were not targets of the district attorneys drug task force. So there was no connection at least at this point that we're aware of to narcotics or to some sort of burglary. My experience tells me that this is a crime committed by someone that's close to the family. 

Lamancusa also said, "And I'm not sure we're ever going to have an answer that would explain a crime like this. I don't think we're ever going to find that moment where they tell us something and we say okay that makes sense, I think that a crime like this is always going to be some sort of senseless violence.  especially when its directed  at a young child who is innocent under any definition."
