Eric Frein’s murder trial continued Wednesday, with new evidence presented in court.
 
Trooper Gerald Gustas took the witness stand, detailing all evidence collected from the Birchwood Airpark in Monroe County, where Frein was caught after a 48-day manhunt.
 
Also in court, it was discovered that Frein may have been keeping a day-by-day journal after the ambush.
 
Trial resumes Thursday.
