( CNN ) Police in Mesa , Arizona , know some things about Ryan Elliot Giroux , accused in a string of shootings that left one man dead and five people wounded . He 's 41 , has an extensive criminal record and served time in prison , according to online inmates records . He 's on probation . Giroux used to have tattoos indicating white supremacist beliefs on his face but apparently had them removed , according to photos . One thing investigators do n't know : What caused Giroux to allegedly go on a deadly rampage . On Thursday morning , Giroux made his first court appearance . He faces multiple charges , including murder , armed robbery with a deadly weapon , kidnapping , aggravated assault and burglary . The prosecutor requested $ 2 million bond and the judge imposed it . Grioux has been sent to prison twice for felonies , including an attempt to commit aggravated assault . He was sentenced to seven years and six months behind bars in July 2007 , but was released in October 2013 , according to online inmate records . His probation runs through October 2016 . He also had a run-in with authorities in Santa Monica , California . He allegedly committed assault with a knife in the early morning hours of March 26 , 2006 , and was detained by witnesses , said Santa Monica Police spokesman Sgt . Rudy Camarena . Giroux was arrested on accusations of attempted murder and parole violation , but police records were n't immediately clear on how the case was resolved , Camarena said Thursday . Police are looking for a motive in the first shooting on Wednesday , but say the other violence happened as the suspect tried to rob people and get away from authorities . The first shots were fired after the suspect got into an argument at the Tri-City Inn with three people that he likely knew , according to Det . Esteban Flores of the Mesa police . One man shot at the Tri-City Inn died , Flores said . Police identified him as David James Williams , 29 , reported CNN affiliate KNXV . The motel is across the street from the East Valley Institute of Technology . According to a police press release , the suspect next shot a man during a carjacking at a nearby restaurant and drove away in a stolen Honda Accord . Grioux tried to carjack another vehicle but failed , police said , and crossed the street to break into an apartment , where he shot and tried to rob a fifth person . He went to another apartment complex and shot a sixth person , police said , before fleeing to a condominium complex . Flores said Mesa 's SWAT team found Grioux in a vacant second-floor condo . Police used a Taser stun gun to subdue him . Police said one man is in critical condition at a hospital , KNXV reported . The other victims , including the mother of the slain man , were treated and released from hospitals , KNXV reported . Authorities on Thursday released a photo of a bruised Giroux in which he had a tattoo on his neck but no tattoos on his face . An Arizona Department of Correction 's photo released earlier showed a heavily tattooed Giroux , with the words `` Skin '' and `` head '' tattooed over his eyebrows . The number 88 was on his left temple , with additional ink on his chin and neck . `` Those are typical tattoos that you do see sometimes on white supremacists , but we do n't know if that has anything to do with what happened today , '' Flores said . Neo-Nazis use the number 88 as an abbreviation for `` Heil Hitler . '' H is the eighth letter in the alphabet , so the Nazi salute becomes 88 in shorthand . Flores said he believes all of the shooting victims were white , with one being white and of Hispanic descent . `` I have no information that his ( Giroux 's ) affiliations or beliefs had anything to do with what occurred today , '' Flores said . News of the shootings caught the attention of the state 's senior U.S. senator . `` My thoughts and prayers are with the victims and families impacted by the tragedy in Mesa today , '' U.S. Sen. John McCain said in a statement released Wednesday . `` Our deepest thanks are with the Valley police and first responders who assisted the victims and tracked down the perpetrator to bring this dangerous situation to an end . '' Mesa is about 20 miles east of Phoenix and is Arizona 's third-largest city .
