Government analyst Joseph Kimani told the court that the straps, which form part of the exhibits he was required to profile, did not link Joseph Irungu, alias Jowie, to them in any way.
The pathologist told Justice James Wakiaga that he received 73 exhibits from the police as well as DNA samples and swabs from several people.
The exhibits for profiling included charred clothes, open shoes, a heavily bloodstained towel, adhesive tape, a knife, a wine glass, an empty beer can and empty beer bottles.
During his cross-examination on Tuesday, Kimani said the DNA on the empty Beer can and the white straps were of different unknown origins.
Irungu is charged alongside journalist Jacque Maribe with murdering Monica on September 19 last year. Her body was found at her Lamuria Gardens Apartment in Kilimani off Dennis Pritt Road.
George Kimani, Monica's brother, on Tuesday told the court that her boyfriend Yassir Mohammed did not attend the burial Kimani "despite informing him about it".
Mohammed was the country director of Caterpillar Inc and lived in the same apartment with Monica.
Kimani also said he was not aware whether Mohammed collected his belongings from the apartment.
Mohammed was to meet Monica on September 20 in Dubai but the meeting never transpired.
Kimani further told the court that he does not know whether the police went to Sudan or Dubai at the time of investigations.
