LINCOLN, Neb. -- A Lincoln man who admitted to shooting his wife is now facing a murder charge.
80-year-old John Kotopka was arrested last month for first-degree assault and use of a weapon to commit a felony.
The Lancaster County Attorney has upgraded those charges this week to first-degree murder.
78-year-old Janet Kotopka died of a gunshot wound in a Lincoln hospital on June 23rd. An investigation revealed her husband was the one who pulled the trigger.
According to court documents, John Kotopka was exhausted from taking care of his wife, who had Alzheimer's, and was concerned about the financial burden if she had to live in a health care facility.
Crime scene technicians processed the scene and located the firearm.
