WAUSAU, WI (WSAU) — A man has been arrested after trying to use a prescription drug to kill his unborn child.

The Wausau Police Department says they arrested 33-year-old Jeffery Smith on February 1st. The investigation into Smith first began on January 28th, according to authorities.

Officers were called to an address on North 3rd Avenue in the City of Wausau on the 28th. When officers arrived, they talked with a woman who was 20 weeks pregnant who reported a concern that the father of the child, Jeffery Smith, put something in her water bottle. She also said that Smith had previously tried to convince her to get an abortion.

The woman said that Smith came to her home on the night of January 27th. She went to the bathroom for a short time and when she returned she found a residue in the bottom of the water bottle.

Police sent the water bottle to the Wisconsin State Crime Laboratory to have tests done on it. Results showed a presence of Mifepristone, which is a drug used to terminate pregnancy.

Wausau Police Detectives then used a search warrant to arrest Smith at his residence in Grand Rapids, WI. Authorities located two empty medication packs at this home. One was for Mifepristone and the other was for Misoprostol. Misoprostol induces labor.

The mother and the baby were not hurt in the incident.

Smith is currently being held on a $500,000 bond.
