Mohamud Bulle sentenced to 19.5 years for 2013 Minneapolis park rape after DNA backlog testing

Mohamud Bulle, 36, was sentenced to 235 months (19.5 years) — 187 months for first‑degree criminal sexual conduct and 48 months for kidnapping, to run consecutively — after a jury convicted him in the Oct. 13, 2013 rape of Melissa Zimmerman in a Minneapolis park. The case was solved after the BCA tested a 2013 sexual‑assault kit in 2020 under the federal SAKI backlog program, producing a DNA profile that linked to another case in May 2024 and to Bulle in October 2024 when his DNA was obtained in an unrelated matter; Hennepin County Attorney Mary Moriarty apologized for earlier delays, and Bulle, who received a separate 36‑month sentence in 2025, is incarcerated at MCF–Rush City with a projected release in March 2038 (248 days credit).

📌 Key Facts

  • Mohamud Bulle, 36, was sentenced to 235 months total (187 months for first‑degree criminal sexual conduct plus 48 months for kidnapping), to be served consecutively — roughly 19.5 years.
  • The victim, identified as Melissa Zimmerman, was assaulted Oct. 13, 2013, after being pushed into a ditch in a Minneapolis park.
  • The case was solved through DNA testing of a 2013 sexual‑assault kit: the BCA tested the kit in 2020 under the federally funded Sexual Assault Kit Initiative (SAKI) after MPD’s backlog of more than 1,700 untested kits was discovered in 2019.
  • The 2020 testing produced an unknown male DNA profile that was later matched in May 2024 to another domestic sexual‑assault case; in Oct. 2024 a court‑ordered DNA sample from Bulle in an unrelated case matched that profile, leading to prosecution.
  • Bulle had previously received a 36‑month sentence in March 2025 for a separate second‑degree assault with a dangerous weapon case involving a shooting and is incarcerated at MCF–Rush City.
  • Hennepin County Attorney Mary Moriarty apologized to victims for delays, said her office has worked through the backlog, re‑contacted victims and filed charges where DNA hits enabled prosecution, and highlighted the role of the SAKI testing effort.
  • Zimmerman and her husband said MPD previously told them the rape kit had been submitted for testing (the husband called that a 'bold‑faced lie'); Zimmerman disputed a criminal‑complaint notation that she had declined to move forward and said she does not recall that conversation.
  • DOC records credit Bulle with 248 days time served and show a projected release date in March 2038 under Minnesota’s two‑thirds rule (making him eligible after serving roughly two‑thirds of the sentence, about 13 years).
