DETROIT — Roughly a week before she was killed along with her six children, Amanda Karolkiewicz of Grand Haven Township posted multiple TikTok videos of a trip she took to China earlier this month with her two daughters.

Smiling and dressed in one post in a traditional Hanfu style of clothing with her makeup and hair done, the 39-year-old called the experience along with her two daughters, Ella and Caroline, the “coolest.” The girls, both 11, were adopted from China.
