President Joseph Biden is ordering flags to be lowered for the eight people killed Thursday evening at a FedEx facility in Indianapolis, Ind.

Friday morning, President Biden issued a proclamation calling for the mark of respect “for the victims of the senseless acts of violence perpetrated on April 15, 2021, in Indianapolis, Indiana.”

US flags are to be lowered, effective immediately, at all public buildings and grounds, at all military posts and naval stations, and on all naval vessels of the Federal Government in the District of Columbia and throughout the United States and its Territories and possessions until sunset Tuesday, April 20, the proclamation noted.

Flags are to also be lowered at all US embassies, legations, consular offices, and other facilities abroad, including all military facilities and naval vessels and stations.

Following suit, Connecticut Governor Ned Lamont also directed US and state flags in Connecticut to fly at half staff, for the same period.

According to the Associate Press, a man started to randomly shoot at people at the facility’s parking lot “late Thursday night.” The man then went into the building and continued firing. The gunman apparently died by suicide shortly before police entered the building.

There was reportedly no confrontation with anyone at the building. Four people were reportedly killed outside the facility, another four were killed inside the building, and “several people” were wounded, including five taken to the hospital, according to AP.

As of early Friday afternoon, the gunman’s identity and motive had not been determined.

The names of those killed and injured had not yet been released by the AP.
