MESA COUNTY, Colo. (KKCO)- The trial of 53 year-old Allen Grabe who shot his young son continued Monday and is wrapping up pretty quick.

Monday's witnesses were personal and professional acquaintances of Grabe, who the defense called to the stand.

These witnesses said Grabe seemed stressed out and confused as to why he lost a contract that was a major source of his window washing business.

They also said he was quiet and talked to himself a lot.

Closing statements are expected Tuesday after the final doctor testifies, and it will be up to the jury to decide if Grabe was insane or sane at the time of the murder.
