Matthew Willson was visiting his girlfriend when he was shot.

The sister of an English astrophysicist who was killed by a stray bullet that traveled through a wall while he was in bed said it was a "senseless act".

Matthew Willson was found with a gunshot wound to the head.

The police were called to an apartment in Atlanta on January 16.

Kate Willson said that everyone who knew her brother had lost a friend.

Ms Willson said her brother was a joy to be around.

She arrived in the US 36 hours after she heard the news.

He was brain dead, and there was little chance he would wake up, because the bullet had caused too much damage to his brain.

Kate Willson said her brother was a wonderful person.

Ms Willson's brother was struck in the head by a bullet.

It was too dangerous for the police to investigate. They had to wait until it was safe to go to my brother.

She said it was a "real pointless act".

Ms Willson said that her brother's girlfriend had been traumatised.

She said she admires her and can't imagine what she's going through.

She said the family had not received any more information from the police.

Somebody knows who did this and who is responsible.

Ms Willson said that the love from everyone who knew Matt was a sign of what a wonderful person he was.
