INDIANAPOLIS — A Sikh civil rights organization called on law enforcement Tuesday to investigate whether a former FedEx employee who fatally shot eight people — four of them Sikhs — at a FedEx facility in Indianapolis last week had any ties to hate groups.

The Sikh Coalition’s request came a day after Indianapolis police released a report from last year stating that an officer who seized a shotgun from Brandon Scott Hole’s home after his arrest in March 2020 saw what he identified as white supremacist websites on Hole’s computer.

The coalition, which identifies itself as the largest Sikh civil rights organization in the U.S., said it has sent letters to law enforcement and state and federal lawmakers “clearly expressing the continuing and urgent need to investigate the possibility of a bias motivation” in last Thursday’s mass shooting.

Hole was arrested last year at his family’s home after his mother told police her son might commit “suicide by cop.” A prosecutor said Monday that after his arrest, Hole never appeared before a judge under Indiana’s “red flag” law, which allows police or courts to seize guns from people who show warning signs of violence.

Hole, 19, used two rifles to kill eight FedEx workers and wound several others inside and outside the facility and then fatally shot himself before police entered the building, authorities have said.

A police report from Hole’s March 2020 arrest states that he became anxious while being handcuffed and asked his arresting officers to cut the power to his computer, saying, “I don’t want anyone to see what’s on it.” The report adds that while securing the shotgun, an officer saw “what through his training and experience” were white supremacist websites on the computer.
