Njoki's younger brother Moses Muchemi said the couple had just returned back to the US after attending their father's burial in Kenya on November 12th.
He said Gary left three weeks earlier since their daughters were resuming school while remaining behind to handle succession matters.
"He left before and my sister stayed one week longer because we were still continuing with succession issues about my father. He would call on a daily basis on WhatsApp and if he does not reach my sister he would call me and ask me if she is okay," he told Citizen TV.
Muchemi said the family was shocked when they received the news of her murder, and could not believe Gary was capable of that because of his nice nature.
"It came as a shock hearing that he did this. For us, he looked like he was a caring man and this was the last thing we expected. Even up to now I don't believe he could do that,” he said.
"Nothing about the couple seemed off to her Kenyan family. The husband greeted us well and liked the children a lot. He would even take my kids out a lot as she did with others including my brother. It's still shocking and we want to wait for investigations from the local police in the States and tell us what really happened."
