NEW YORK - Police in the US state of Indiana have not yet established a motive for the "execution-style" murders of three young Muslim-American men last week, according to media reports.

Authorities say they found the bodies of Fort Wayne residents Mohamedtaha Omar, 23, Adam K. Mekki, 20, and Muhannad A. Tairab, 17, inside a local home on Wednesday. Whoever killed them shot each man multiple times.

But the in brutal slaying of Muslims, who police said hailed from Africa's eastern Sahel region,has barely caused a ripple in mainstream media in the United States

Police said the murders were not believed to be gang-related. The killings came in the same week that other mass shootings in the US gained widespread coverage, nationally and internationally.

Last Saturday night, a man identified as Jason Dalton drove around the Michigan city of Kalamazoo and randomly shot people, leaving at least six dead.

Then on Thursday, three people were killed and at least 14 others wounded by a gunman in a series of shootings in the state of Kansas.

After major online news site Vox published a piece on the Fort Wayne shootings on Saturday, many took to social media to question why there had not been more coverage.
