(CNN) -- A random act of violence has left a promising 22-year-old college baseball player dead, a family devastated and two countries half a world apart rattled.
Christopher Lane, who's from Australia, was gunned down in Duncan, Oklahoma, while he was out jogging last week. The motive? Three teens who had nothing better to do, according to police.
"They witnessed a young man run by on the street. Chose him as the target," Police Chief Danny Ford told CNN affiliate KSWO.
When police eventually arrested the three teens -- ages 15, 16 and 17 -- one of them offered up a motive that made clear that Lane, who attended East Central University on a baseball scholarship, was chosen at random.
"He said the motive was, 'We were going to kill somebody,'" Ford told Australian radio station 3AW.
"They decided all three of them were going to kill somebody."
A brutal crime
Police say the teens shot Lane in the back in the town of about 24,000 and sped away in their car.
"There were some people that saw him stagger across the road, go to a kneeling position and collapse on the side of the road," Ford told KSWO.
Attempts to revive Lane failed.
Police caught the teens a few hours after the shooting. Thanks to security cameras from local businesses, police saw their car speeding down the street.
Details of pending charges against the teens have not yet been released. They were scheduled to appear in court Tuesday afternoon.
Half a world away
Nearly 10,000 miles away in Australia, Lane's family struggled to cope with the news.
"He's left his mark as we know, and you know there's not going to be any good come out of this, because it was just so senseless," Christopher's father, Peter Lane, said. "It's happened. It's wrong, and we're just trying and deal with it the best we can."
Lane's girlfriend, Sarah Harper, posted an emotional tribute on Facebook, saying "you will always be mine and in a very special and protected place in my heart."
Friends and strangers alike posted condolences on another Facebook page, honoring the slain baseball player.
"Such a sad waste of a young man's life," one poster wrote.
"Know that many Americans are sorry for this tragedy and want justice for Chris," wrote another. "God bless."
