According Yami Virgin reporter at KABB and WOAI, LE did not want a side profile in her missing posters. LE wanted a frontal profile. So, this was probably why these pictures were not released immediately.

Lina's family traveled to Afghanistan in 2021. It has been discussed here on WS and is documented here:
Surviving the atrocities of war just to disappear in the United States: Lina Sardar Khil still missing after three weeks.
I think she looks much younger in the Afghanistan picture because she has bangs. (JMO)
You can watch this video to see pictures of Lina various ages. Video was approved by WS mods:
You can also google for images. Lina had shorter hair when she was living in Afghanistan.
