A Wisconsin woman was in court Monday for killing her friend with a lethal dose of eye drops.

According to a criminal complaint, the 37-year-old called police in October 2018 saying her friend was unconscious and not breathing.

Initially, investigators believed it was a drug overdose.

However, in January 2019, toxicology tests revealed the woman had a lethal dose of the main ingredient found in eye drops in her system.

The woman also allegedly transferred thousands of dollars from the victim's account to her own.
