[7] The building is equipped with metal detectors and security turnstiles at its entrance requiring the employees to scan their FedEx badges.

[2] According to Indianapolis police, Hole began firing at employees in the parking lot with a rifle shortly after exiting his vehicle again.

[1][4][6] The following were killed in the shooting: Matthew Alexander, 32; Samaria Blackwell, 19; Amarjeet Johal, 66; Jasvinder Kaur, 50; Amarjit Sekhon, 48; Jaswinder Singh, 68; Karli Smith, 19; and John Weisert, 74.

[2] In March 2020, Hole's mother contacted the local authorities and warned them about her son's intent to die by suicide by cop and his purchase of a shotgun the day before, prompting an investigation to be opened.

[12][27][28] Hole was placed in an "immediate detention mental health temporary hold" by the Indianapolis Metropolitan Police Department, but he was released after less than two hours.

The investigation was later closed due to insufficient evidence of any criminal violation or a racially motivated extremist ideology held by Hole, though the shotgun was not returned to him.

[30][31] According to the police, Hole used two AR-15 style rifles in the shooting, and both of them were legally purchased from a licensed gun store in July and September 2020.

[28][32] Under Indiana's red flag law, Hole could have been prevented from making firearm purchases for at least six months after his temporary mental health detainment if a hearing had been scheduled with a judge fourteen days after the seizure of his shotgun.

However, Marion County prosecutors decided not to schedule such a hearing, believing authorities had already achieved the law's objective since Hole's family did not want the seized shotgun back.

Later, during a press conference with Japanese Prime Minister Yoshihide Suga, Biden decried the recent string of mass shootings in the United States as a "national embarrassment" and called on Congress to ban military-style assault weapons and large-capacity ammunition magazines.

[38] On April 20, Governor Eric Holcomb announced his intention to restore full funding for mental health services and bolster it over the next two years.

[39] Democratic state politicians made calls to review and strengthen the red flag law, but this was put on hold after the 2021 legislative session ended on April 22.

[42][43][44] On April 19, FedEx established a GoFundMe campaign through the National Compassion Fund to collect donations supporting survivors and the families of victims.

[47] On April 13, 2023, victims and families of the shooting filed a lawsuit against the U.S. distributor of the high-capacity magazine (60 rounds) used in the assault, American Tactical Inc., two company executives, and the German manufacturer, Schmeisser GmbH.
