A 42-year-old Mainland man has been indicted on charges of attempting to murder a security guard by pushing him out a window on the 26th floor of a University Avenue condominium.

Joseph R. Joyce, who has no local address, was also indicted on charges of attempted burglary of a condo unit in the same building, attempted assault of a condo resident and terroristic threatening.

He is being held in lieu of $500,000 bail pending trial.

Joyce allegedly pushed security guard John Lopis, 63, into a window pane Friday afternoon after Lopis confronted him in a hallway of the building. The window shattered and Lopis fell through the opening, holding onto the window frame and dangling 26 floors above the street.

Joyce is also charged with the attempted assault of Pierre Jaffuel, 77, a resident on the floor who had come out of his unit to investigate loud noises in the hallway.

Joyce also allegedly threatened Jaffuel.

He's also charged with attempted burglary of another man's residence on the same floor.
