CNN - The Marines said Mohassib’s “premature discharge is indicative that his service was incongruent with Marine Corps’ expectations and standards.”

WHAT:

CNN - The criminal complaint says Suarez was found bleeding heavily from the neck, taken to a hospital and died from her injuries.

CNN - Prosecutors said Mohassib told police he went to the path with a knife because “people were going to come and kill his family.” He said he sat on a bench, became covered in blood and had not stabbed anyone; prosecutors said he described disposing of bloody clothes and a knife and cleaning blood from his hands and apartment.

CNN - Mohassib confirmed to detectives that he appeared in the surveillance video.
