Trial judge Jessie Lessit heard that Kamande became angry at the 24-year old after discovering several letters.
“She was angry and demanded to know why he still kept the letters,” Mohammed's uncle Edward Gatonye told the court.
Gatonye said the couple had planned to attend a party a day before Mohammed was found lying in a pool of blood at his rental house in Buru Buru estate, Nairobi.
He told the court he decided to go to his nephew's home after failing to reach him by phone.
“I found him at home with Kamande. We used to call her Biggy. When I inquired why his phone was off, Farid told me she had blocked it," he said.
"He also told me she was unhappy because she had found old high school letters from women."
Gatonye said he got worried after Kamande left them in the sitting room and locked herself in the bedroom.
The uncle, who said he met the woman just two months before the incident, noted he found her action disturbing. He said Kamande only came out of the room at lunch time to buy chips which she served herself and Mohammed.
“Farid had previously complained to me about her. He told me she was forcing him to let her stay with him yet he did not want this,” he said.
Mohammed's sister Serah Waithera, who was called as the third witness, described the couple's relationship as stormy and one-sided. Waithera said Kamande pushed her brother too far and that her expectations did not match his.
“She came to my workplace and introduced herself as my brother’s girlfriend," she told the court.
"From then on she would complain to me when they had problems but my brother would deny their relationship. One time I advised her not to force the relationship."
Kamande denied brutally murdering Mohammed on September 20, 2015.
The trial will resume on November 25.
