1. Hernandez kills self: Aaron Hernandez, the former NFL star who was serving life in prison for murder, committed suicide in his cell Wednesday morning, according to the Massachusetts Department of Corrections. The former New England Patriots star was discovered hanging in his cell at the Souza Baranowski Correctional Center in Shirley, Massachusetts, at 3:05 a.m., according to officials. "Mr. Hernandez was in a single cell in a general population unit," a statement said. "Mr. Hernandez hanged himself utilizing a bed sheet that he attached to his cell window. Mr. Hernandez also attempted to block his door from the inside by jamming the door with various items."

2. Wanted to kill whites: A man in Fresno, California, who said he wanted to kill as many white people as he could, shot and killed three men at random, all within a city block, on Tuesday.

3. Election heads to runoff: A Georgia special election will be decided in a runoff in June after none of the 18 candidates on the ballot got more than 50 percent of the vote. Democrat Jon Ossoff, who garnered national attention and support for his run for the seat vacated by Tom Price, narrowly missed the 50 percent mark and winning the race outright. Price resigned from the House when he became President Donald Trump's health and human services secretary. Ossoff will face Republican Karen Handel, a former Georgia secretary of state, in the June 20 runoff.

5. Walmart discounts:

Starting Wednesday, Walmart will begin discounting thousands of items that customers order online and pick up at local stores. According to the company, some 10,000 items will initially be discounted, with that number growing to 1 million items by early summer.
