It was the police that initially strongly implied that it was an honor killing:

A Minnesota man is accused of killing his 20-year-old stepdaughter in Michigan because she left home and wasn’t following Islam, police said Tuesday.

[…]

Torey said Mokdad had left her mother and stepfather to live with her father near Flint in Grand Blanc because she did not like their rules.

“He’s a strict Muslim, she was more Americanized,” Torey said.

Now this seems to be a result of lazy thinking/stereotyping, since:

Authorities previously said Alfetlawi was angry because Mokdad left home and wasn’t following Islam. The Macomb Daily of Mount Clemens reports prosecutors now say religion wasn’t an issue and Mokdad’s biological father was targeted.

So while Geller could be excused for initially assuming it was an honor killing, she should certainly address the facts of the case on their own merit before asserting it any further, and especially using it as a propaganda device.
