( CNN ) -- The suspect charged with murder in last week 's shooting that left one person dead and two wounded at Seattle Pacific University wrote a journal entry on the morning of the shooting stating `` I just want people to die , and I 'm going to die with them , '' prosecutors said . In the weeks before the shooting , Aaron Ybarra , 26 , kept a journal in which he allegedly expressed `` admiration for the perpetrators of other incidents of mass violence -- at Columbine High School and at Virginia Tech University , '' King County Prosecuting Attorney Dan Satterberg said . Satterberg said the entries also indicate Ybarra had considered shooting people at other campuses in Washington state but chose SPU shortly before the incident . He was n't a student at the school . Ybarra is charged with one count of murder in the first degree and two counts of attempted murder in the first degree , prosecutors announced Tuesday . Prosecutors will seek a special sentence of life in prison , Satterberg said . Ybarra typically would face 69 to 86 years in prison if convicted of the charges , but prosecutors will argue that an aggravating factor -- a `` destructive and foreseeable impact on persons beyond the victims '' -- allows for a life sentence . Ybarra is scheduled to be arraigned June 23 , Satterberg said . Counselors and friendly friends even showed Ybarra around the campus in the days before the shooting , and he allegedly carried out the minute-long shooting just before the academic year ended , Satterberg said . Ybarra allegedly kept the journal in anticipation that he would die in the attack , the prosecutor said . Ybarra allegedly went to the campus armed with a 12-caliber double-barrel shotgun with 50 rounds in his pockets . But the gun malfunctioned , rendering the double-barrel shotgun into a single-barrel one , the prosecutor said . Ybarra allegedly fired only two shots -- killing one student and wounding two others -- before student security guard Jon Meis pepper-sprayed Ybarra 's eyes and took away the shotgun , Satterberg said . Meis put the shotgun in his office and returned to take a large hunting knife away from Ybarra , Satterberg alleged . Another student assisted in allegedly disarming Ybarra , kicking the knife out of reach , Satterberg said . `` Jon Meis is an authentic hero , '' Satterberg said . `` He saved many more lives . '' During the shooting , one student was wearing headphones and was oblivious to the noise and the fact that a shotgun was pointed at him , Satterberg said . The gunman decided not to shoot the students , Satterberg said . `` Just as suddenly as this crime erupted , it was over , '' Satterberg said . `` The whole thing took less than a minute . '' Ybarra is accused of fatally shooting Paul Lee , a 19-year-old student , in the back of the head , Satterberg said . One of the wounded , a 19-year-old woman , underwent surgery after the shooting , Susan Gregg of Harborview Medical Center said . A second victim , a 24-year-old man , was discharged Friday , she said . The shooting at the university on Thursday afternoon began when a man armed with a shotgun opened fire outside and inside Otto Harris Hall , which houses the engineering , math and science departments . Ybarra has a history of mental health problems and was on suicide watch last week at the jail , public defender Ramona Brandes said . Ybarra has `` significant and long-standing mental health issues , including delusions that were in play '' at the time of the shooting , she told reporters last week . `` ... He 's on suicide watch for a reason . He did not think he was going to survive yesterday . He intended to die . '' Brandes said Ybarra was aware of what happened . `` He is cognizant of the suffering of the victims and their families and the entire Seattle Pacific community , '' she said . `` He is sorry . '' Ybarra had had several run-ins with police in recent years . He was taken into custody in 2010 and 2012 for a mental health hold , Mountlake Terrace Assistant Police Chief Pete Caw told CNN . In both cases , authorities determined Ybarra was intoxicated , incoherent and suicidal , Caw said . The image of the suspect as a gun-toting killer is a difficult one to reconcile for those who know him . One friend described Ybarra as `` socially awkward '' but `` appreciative , '' according to KOMO . `` I have no idea what set him off , '' said Nate Flesch . `` That 's why this whole thing kind of surprises me -- that he was trying to turn his life around , that he was trying to be a better person , and he was kind of working on his social skills , too . '' CNN 's Chelsea J. Carter , Greg Morrison , AnneClaire Stapleton , Suzanne Presto and Ben Brumfield contributed to this report .
