U.S. Sen. Amy Klobuchar is behind a new bill that would make it easier to call 911.

The legislation stems from a 2013 murder where Kari Rene Hunt of Marshall, Texas, was killed in a hotel room by her estranged husband.

The woman’s 9-year-old daughter tried to call 911 but could not because she did not dial “9” to reach an outside line.

If the bill, called Kari’s Law, passes, it would require phone manufacturers to create systems that allow callers to reach 911 without having to dial any extra numbers.

“We should be doing everything we can to make sure that contacting emergency personnel is as simple and easy as possible,” Klobuchar said in a statement. “This bipartisan bill will build on the progress already made by industry leaders and help ensure a tragedy like Kari’s never happens again.”
