A 54-year-old man was arrested in connection with the shooting death of his 53-year-old wife Monday night in Mesa, police said.

Alvin Johnson Jr. gave contradictory statements to police following the 11:30 p.m. shooting near 14th and Center streets, Mesa police said.

Upon arriving at the residence, officers saw Johnson, who had his hands up and repeatedly said, "I did it, arrest me," to officers, police said.

The body of an adult female, later identified as 53-year-old Michelle Lynne Johnson, was found inside the residence, police said.

Other family members were present during the incident and witnesses stated Alvin Johnson Jr. was heard saying "I killed her" and "I'm going to prison, call the cops," police said.

Alvin Johnson Jr. told officers he "did not mean to kill her," and that he had been drinking at a football game and that when he returned home and climbed into bed the gun accidentally went off and struck his wife, police said.

Police said some of the man's statements indicated his wife was awake at the time of the shooting while others indicated she was sleeping.

He said his drinking "may have impaired his memory of what happened," and said he was recklessly handling the gun, Mesa police said.

He was arrested and is facing one count of second-degree murder.
