Kayla Ashlyn Bonkowski, 19, is due in an Isabella County courtroom Monday on the felony poisoning charge. Bonkowski was named in a warrant issued by prosecutors following a report about the Nov. 11 incident.
Reached by email, Bonkowski told The Associated Press on Wednesday morning she needed to consult with a lawyer before commenting.
Investigators say Bonkowski and her roommate were involved in a dispute over dirty dishes in the home they shared.
Authorities say they believe Bonkowski put bleach in the drink at the apartment in Union Township, located near the Mount Pleasant school about 120 miles northwest of Detroit. Police say the roommate was taken to an area hospital for treatment.
