USA Adrian, son of millionaire Brian Bonar, is crammed into the trunk of a car left on the California highway.

Anaheim City police, California, USA on October 29 said they suspected Adrian Bonar, 34, was killed by the notorious MS-13 gang in Los Angeles. The MS-13 gang was once called "ferocious monsters" by US President Donald Trump.

Highway patrol officers spotted a Lexus left on the highway on the morning of October 17. When preparing to pull the car, they discovered in the trunk of the car is a body wrapped in blue tarpaulin, taped. The victim was later identified as Adrian.

Adrian is most likely being controlled and murdered by a dangerous criminal group. "The police are investigating the motives of the murders but it is clear that they are willing to use the worst violence without thinking," police sources said. "He could be the victim of a bigger dispute."

Adrian is the son of Scottish millionaire Brian Bonar, who joined the US military and was sent to Iraq in 2007-2008. His mother last week flew from Scotland to the United States to attend a memorial for her son. Adrian's coffin is covered with the American flag in the military tradition.

Pauline Gourdie, Adrian's sister, 48, said that her brother's killers "deserve to rot in the sewer of hell". She also expressed the pain of losing her brother, saying that she was extremely proud to be Adrian's sister.
