LOS ANGELES , California ( CNN ) -- The man who police say dressed as Santa Claus and killed nine people at a Christmas Eve party may have also had plans to kill his mother and his former wife 's divorce attorney , police said Monday night . Bruce Jeffrey Pardo went on a shooting rampage in a Los Angeles suburb on Wednesday , police say . Prime suspect Bruce Jeffrey Pardo , who police said committed suicide hours after he went on a shooting rampage and started a raging house fire in the Los Angeles suburb of Covina , left a rental car with a gasoline canister outside the home of attorney Scott Nord , said Pat Buchanan of the Covina Police Department . Police previously said that Pardo targeted his rampage at his former wife , Sylvia Ortega Pardo , and her family at the family 's Christmas Eve party . A divorce between the two was finalized in court on December 18 in a `` somewhat contentious proceeding , '' Covina Police Chief Kim Raney said last week . Police believe Pardo planned to carry out a similar attack at Nord 's house as he did at the shooting and house fire that claimed nine lives . Another rented car that Pardo used to flee the scene was found booby-trapped after the shooting , police said . That car burned as the Covina bomb squad was trying to disconnect an explosive device in it , police said . On Saturday , Covina police released the names of the nine people unaccounted for since the shooting and fire . Nine bodies were recovered from the rubble of the house , but authorities said that they are having to work with dental records to establish identities . `` The bodies were so badly burned they can not be identified any other way , '' said Covina police Lt. Pat Buchanan . The nine unaccounted for include Sylvia Pardo , her parents , her sister , her two brothers , both brothers ' wives , and a nephew . Ages of the nine range from 17 to 80 , police said . On Monday night , police said Pardo 's mother had also planned to attend the Christmas party , but did n't go because she was sick . Pardo had a contentious relationship with his mother , according to Buchanan , because she attended the couple 's divorce hearing and had sided with Pardo 's ex-wife . The shooting and fire left 10 children orphaned and three others lost one parent . An `` Ortega Family Fund '' has been set up at Nord 's law offices .
Police say Bruce Jeffrey Pardo had the list after divorce proceedings were final . Original target was Pardo 's ex - wife , police say , but attorney , mom also say . Shooting and fire left 10 children orphaned and three others lost a parent .
