Court documents provide new information in the August 2016 murders of three people in Newton County, Indiana.
23-year old Richard Thomas, 39-year-old Kimberly Spears and 20-year-old Justin Babbs were all found stabbed inside a home in Sumava Resorts.
Sebastian Wedding was arrested. He allegedly told a witness he needed gas money because he planned to leave the state.
The Court documents say police monitored Facebook message conversations between the witness and Wedding later that day.
Wedding allegedly admitted to being at the home where the murders took place.
Wedding was arrested August 29. Two days later, Derrick Cardosi was arrested after a witness saw him at the scene in the days following the murder.
Investigators have not commented on a possible motive.
Wedding and Cardosi pleaded not guilty to 3-counts of murder, auto theft and theft in September. In December, they both pleaded not guilty to an additional 2-counts of murder.
Prosecutors plan to seek life without parole.
