US Joe Melgoza, 30, died after being assaulted by two "uninvited guests" with a baseball bat at a wedding reception in Chino, California.

Joe Melgoza was spotted in the backyard of a wedding venue in Chino City, California, on the morning of December 15, police said. He was seriously injured in the head and was transferred to the hospital but did not survive.

Police soon arrested suspect Rony Aristides Castaneda Ramirez, 28, and his younger brother Daniel Castaneda Ramirez, 19, at a house near the scene.

"My brother didn't deserve to die like that. He was a good person. He was a tough man," said the victim's brother, Velasquez.

The two suspects were not invited to the wedding but were deliberately disturbed and asked to leave the party. The two men then returned, using a baseball bat to attack the groom, killing him. Two others also suffered minor injuries. The police are investigating the incident.
