Edward Batzig Jr., 16; Domenic Coia, 18; and his brother, Nicholas Coia, 16, are all charged with murder.
Yesterday, prosecutors filed court paperwork indicating aggravating circumstances - the first formal step in seeking death sentences for the boys. Morley is ineligible for the death penalty because of her age.
The teens, who all remain jailed without bail, were not required to attend the brief arraignment hearing.
Sweeney's father, Paul, sat in the courtroom and vowed to attend every hearing in the case.
"Straight up - the death penalty is what I want," he said after the hearing.
Paul and Dawn Sweeney recently established the Jason Keel Sweeney Foundation to fund a scholarship to the Valley Forge Military Academy in memory of their son.
"We're looking for a C student, and a C student only, who's in financial need and really wants to go there," Dawn Sweeney said.
The foundation will be holding a July 31 fund-raiser and silent auction from 7 to 10 p.m. at Liberties restaurant, 705 N. Second St. Dawn Sweeney said $25 tickets would be sold at the door.
Contributions may be sent to the Jason Keel Sweeney Foundation, Box 3775, Philadelphia 19125.
The next court listing for the four teens is scheduled for Aug. 19. Brennan said a judge was unlikely to hear arguments on his motion to move Morley's case to Family Court until after that date.
