A suspect accused of killing two people and injuring six others during a shooting spree at Florida State University did not know his victims, police said Friday.

The alleged gunman, 20-year-old FSU student Phoenix Ikner, began shooting around lunchtime on Thursday near the student union building in Tallahassee. The motive remains unclear.

The biological mom of suspected Florida State University shooter Phoenix Ikner claimed she has not seen her estranged son in several years after she abducted him to Europe a decade ago — but had concerns over his well-being.

Anne-Mari Eriksen said she had concerns for her 20-year-old son before he was accused of killing Aramark employees Tiru Chabba, 45, and Robert Morales, and injuring six others on the campus located in Tallahassee.

The 20-year-old student accused of killing two people and wounding six others at Florida State University had expressed extremist political views that made classmates uncomfortable, talked about his interest in guns and experienced years of family tumult that culminated in his changing his name in high school.

Colorado Gov. Jared Polis (D), signed a bill into law on April 10 requiring people to obtain a permit and undergo safety training before they buy certain guns.

The legislation also bans the purchase and sale of devices that enable guns to be fired rapidly, including bump stocks.

“For folks who haven’t had any gun safety training, it’s very important that they get that, and this bill will make sure that people will get that education on how to operate the weapons safely and—just as important—how to store them safely,” Polis said at a press conference on Thursday.

Although President Donald Trump has been entrusted with control of the nation's vast military might, including its nuclear weapons, he is not allowed to own a gun. He lost that right as a result of 34 state felony convictions involving falsification of business records. Whatever you think of the legally dubious case underlying those convictions, this situation makes no sense as a matter of public safety. It epitomizes the absurdly broad criteria that bar Americans from possessing firearms under federal law.

The Supreme Court held Wednesday that federal firearms laws cover so-called ghost guns, weapons that are assembled from kits that law enforcement says are becoming the go-to choice for armed criminals. 

The gun industry had challenged a Biden-era regulation treating ghost guns like other firearms, with the same licensing, background checks and serial number requirements. A federal appeals court in New Orleans had set aside the regulation, reasoning that weapons parts aren’t weapons and thus weren’t covered by the Gun Control Act of 1968.

The Supreme Court upheld a federal rule targeting ghost guns on Wednesday, preserving a key Biden-era regulation that treats “readily convertible” gun kits, commonly referred to as “ghost guns” due to their often untraceable characteristics, as firearms under federal law.

The Supreme Court on Wednesday upheld a federal ban on the sale of parts kits that permit unlicensed gun owners to make firearms at home which cannot be traced by the police.

In a 7-2 decision, the justices agreed these homemade weapons, often referred to as “ghost guns,” qualify as firearms under federal law.

 The Supreme Court on Wednesday upheld a Biden administration effort to regulate “ghost gun” kits that allow people to easily obtain parts needed to assemble firearms from online sellers.

The decision by a court that often backs gun rights resolves the legal dispute over whether the kits can be regulated the same way as other firearms.

The Supreme Court will hear arguments Tuesday in a $10 billion lawsuit Mexico filed against top firearm manufacturers in the U.S., alleging their business practices have fueled cartel gun violence.

The gun makers reject those claims. They appealed to the Supreme Court to overturn a ruling that let the lawsuit move forward even though U.S. law largely shields gun makers from lawsuits.
