Police are investigating whether a man suspected of shooting dead 14 people at a university in Prague was behind a double murder last week.
They confirmed the possible link after searching the house of the 24-year-old - who also died after yesterday's attack.
His father was found dead, too.
Detectives are trying to work out the student's motive.
Local journalist Michal Tomes says they've reportedly found a social media post of interest to them:
"It was a telegram account where he published his thoughts. About was basically about how he hates this world and how nobody loves him, and information like this".
