Desiree Marie Franken, 40, of Rochester pleaded guilty on Thursday in Mower County District Court to felony second-degree manslaughter-culpable negligence creating unreasonable risk.

Charges of felony third-degree murder-drugs and felony third-degree murder-sale of a narcotic will be dismissed at the sentencing.

Court documents state a woman was found unresponsive on June 7, 2017, in her bed at her residence in the 800 block of Eighth Avenue Southeast. Gold Cross and a medical examiner also responded to the scene and pronounced the woman dead. Police found used syringes on the floor and in a drawer next to the bed. They also found a pill bottle with two bags of methamphetamine and a bag of heroin as well as a tin cup with a cotton ball inside, which is consistent with injecting heroin or other drugs.

The victim’s mother told police the victim was an opiate abuser and that Franken had visited her during the late night hours of June 6, 2017, and did not leave until 6 a.m. the next morning, according to court documents. An autopsy revealed the victim died of “heroin, fentanyl and methamphetamine toxicity.”

Court documents state a review of the victim’s cell phone showed text messages exchanged between her and Franken from June 4-6, 2017. In them, the victim agreed to purchase three grams of heroin for $225 from Franken. A message from Franken, sent at 11:36 p.m. on June 6, 2017, said she was coming to the victim’s house.

Police executed a search warrant of Franken’s Rochester residence on June 8, 2017. Franken admitted she sold the victim heroin on the night on June 6, 2017.

In Minnesota, the maximum prison sentence for second-degree manslaughter is 10 years.

Franken will be sentenced on Jan. 31.
