Hans Campos accused of shooting dead a guest at his Super Bowl party after inviting a group of friends over to watch the game

An Arizona man has been accused of shooting dead a guest at his Super Bowl party after inviting a group of friends over to watch the game.

Hans Campos was arrested on suspicion of second-degree murder following the death of 31-year-old Gregory Simmons.

Witnesses say Campos shot and killed Simmons after getting into a drunken argument with him.

Campos is said to have invited Gregory and three others to his Phoenix home to watch the game between the LA Rams and the New England Patriots on Sunday.

A report filed in Maricopa County Superior Court said Campos was intoxicated when he invited them to watch the game.

Witnesses said he then continued to drink to a level that made one of those at the party 'feel uncomfortable'.

Campos is even reported to have pulled out his handgun during the evening.

When that party-goer left Campos and his alleged victim are said to have started arguing. The remaining people watching the game at the home also decided to leave but Simmons is said to have stayed.

An official reports says when they then heard gunshots the two witnesses ran to Gregory's apartment and told his girlfriend to call the police.

There officers reportedly found Campos intoxicated. He is then alleged to have said: 'Better him than me.'

The shooting happened at an apartment complex in the 2600 block of North 51st Avenue, pictured, according to police

Police were called to the apartment block after the row at around 10pm on Sunday night. Campos was arrested early Monday.

Simmons was taken to a nearby hospital with two gun shots to the front of his body and four to his back and later died, AZ Central reports.

Campos is being held on $1 million bond and will appear in court next Monday. He claims to have fired his gun in self defense.

He said he used the gun as previous injuries means he can't use his fists, according to a court document.
