Police have received toxicology results for the two brothers, Harrington and Joshua Mbeleko, three months after their deaths in Kasama.
Police Public Relations Officer Godfrey Chilabi has confirmed that the results were handed over and will be reviewed jointly with the family on Monday.
The brothers, who worked for a fitment company in Lusaka, were found dead in their room after traveling to Kasama for work.
Mr. Chilabi has acknowledged communication challenges between police and the family, which had raised concerns over delays.
Meanwhile, the Human Rights Commission has called for the establishment of a local forensic laboratory to speed up investigations.
