Jaison Muvevi who is facing multiple murder charges has been cleared of six charges following ballistic tests.
He was being investigated for killing up to 10 people.
Muvevi, a former police detective, was in the news following a January shooting spree in Hwedza in which three people died and two more narrowly escaped death.
He was arrested in Mozambique.
Muvevi was also linked to another suspected murder that took place in November 2022 in Eastlea, Harare.
Police were eager to find out if he had any connection to the six previous unsolved murder cases that had occurred in Harare and Chitungwiza since 2020.
Muvevi’s suspected murder weapon was taken for ballistic tests about a month ago to try to link the forensic evidence to these six cold cases.
