This is The Guardian.

One night, in May 2013, Alex Via and a buddy drove to a movie theater in Rosemont, a suburb

just outside Chicago. It had been more than a year since Officer Lewis was killed. They parked

in a garage next to the theater, cate a late showing of the Hangover 3, then headed back

to their car. But Alex never made it.

Minutes after the movie ended,

he was lying at the bottom of a parking lot stairwell

in a pool of blood.

A few hours later,

Alex's sister Marisol got a phone call,

telling her Alex was in the emergency room.

So he was hit with a golf club in the back of the head or something.

And then he was stabbed with like a box cutter blade multiple times on his arms.

Four attackers had jumped Alex in the stairwell.

His friend said Alex was behind him as they walked up the stairs.

Then he heard him scream and turned to see Alex on the ground as the men pounded him.

The whole encounter lasted just a minute, leaving Alex with a broken hand and three stab wounds

and the attacker screeching off in a waiting car.

Alex's friend didn't recognize any of the people.

And the thing the sisters couldn't figure out is who would follow Alex to a movie theater in Rosemont

and wait for him to come out and then attack him.

It didn't seem random.
