Shayne Carpenter had a fight with his girlfriend and it led him to take strange measures.

Carpenter began spiking the woman’s drinks with Visine and making her sick. She found out about the plan when she read text messages on his phone that bragged to his friends about what he had done.

Police in Grass Valley, California worked with the woman to catch the creep.

Cops asked her to call Carpenter while they were listening. She did and he admitted his actions and shortly after he was taken into custody.

Carpenter is being charged with domestic violence and poisoning.
