"I had fun," suspect Randall Rushing, 25, told reporters, smiling and blowing them a kiss as he was led into court after his arrest Thursday afternoon.
Rushing yawned throughout his arraignment on three homicide counts. District Judge James Gibbons advised him to invoke his right to remain silent.
The victims - Justin Berrios, 21; Dustin Hintz, 22; and Leslie Collier, 16 - were found dead in a south Scranton residence by police responding to a 911 call just before 7 a.m. Thursday, authorities said.
Four other people were found in the house unharmed. At least some of the survivors had been bound, Jarbola said. One of them, a 19-year-old woman, had recently ended a relationship with Rushing, according to court papers.
Investigators believe the attacks occurred between 4 and 6:30 a.m. Thursday.
"He had a gun on his person. That we do know," Jarbola said.
Following a daylong search for the suspect, authorities set up surveillance around a Wilkes-Barre apartment building after a car registered to the woman was found parked in the area, police said. A SWAT team swarmed in and arrested Rushing shortly after 4 p.m.
Scranton is in northeastern Pennsylvania, about 100 miles north of Philadelphia.
