( CNN ) -- A former policeman is on trial in Kansas , accused of killing his wife and setting their home on fire more than two years ago . Attorneys for Brett Seacat say his wife , Vashti , started the fire and shot herself . But prosecutors say he was upset about the dissolution of their marriage , giving him more than enough motive . On Monday , jurors heard from the Seacats ' marriage counselor , CNN affiliate KWCH reported . Connie Suderman testified that Seacat called her just hours after his wife 's death in April 2011 . `` He said , ' I killed her , Vashti is dead and it 's my fault . ' That 's what he said , '' Suderman said , according to KWCH . The counselor also testified that she met with Vashti Seacat shortly before her death . She purportedly told Suderman she was worried about how her husband was handling their divorce but was happier than she 'd been in years . CNN affiliate KSN reported the counselor also testified about a conversation she and Vashti Seacat had about suicide . `` She could n't do that to her boys . She elaborated by saying that she loved being a mom . She could n't leave them . They needed her , '' Suderman said . Those sentiments were echoed Monday by Vashti Seacat 's friend , Erika Head , who spoke to HLN 's Nancy Grace . `` She was very happy with her life , and she knew that things were looking up , '' Head said about Seacat , saying she was `` never , ever '' suicidal . Brett Seacat and the couple 's two sons were at home the night of the fire . Prosecutors and the defense differ about exactly what happened . Brett Seacat says he was sleeping downstairs and heard a noise , KWCH reported . Moments later , his wife called him on his cell phone , saying he should get their boys before they got hurt . He then purportedly heard two pops . Brett Seacat went upstairs and saw flames . He reportedly says he found his wife in their bedroom and tried to save her . But prosecutors say Brett Seacat 's story does n't makes sense . For one , he had no soot or blood on him , they say , according to KWCH , and only a small burn on his foot . He and the couple 's sons escaped from the blaze unharmed . The Seacats ' home in Kingman , Kansas , sits not far from the courthouse where Brett Seacat is standing trial . Despite extensive fire damage , the house still stands ; a brick chimney pokes out of the charred remains . `` I 'm smart enough that if I wanted to kill my wife ... I could 've come up with something better than this , '' Brett Seacat told investigators about the shooting and the fire . `` This is what a crazy person does . '' HLN 's Amanda Sloane contributed to this report .
