A Mesa woman who police say fatally shot her boyfriend after he accused her of having an affair and had a physical fight with her, was arrested on suspicion of second-degree murder late Sunday.

Donna Diaz, 52, who called 911 and told a dispatcher she shot her boyfriend, was arrested without incident about 11 p.m. in the 1200 block of South 76th Place minutes after police responded to the call.

Diaz complied with officers' orders to come out of the residence moments before police discovered the body of her boyfriend, Thomas Mark Wakeham, lying on the kitchen floor with three gunshot wounds to his chest. He was pronounced dead at the scene.

Diaz, who police say admitted shooting Wakeham, said she and her boyfriend were drinking at a local bar earlier in the day. They returned home and Diaz fell asleep in her bedroom. Her boyfriend woke her up and accused her of having an affair after looking at her cell phone.

According to Diaz, Wakeham then grabbed her by her ankles and pulled her out of bed and dragged her into the kitchen area. She said she ran back to her room and hid in a closet where Wakeham found her and again grabbed her and dragged her back out.

Diaz again was able to run to the closet where she said she retrieved a handgun, according to police.

Diaz said she then confronted her boyfriend with the handgun as he was seated on a couch in the living room. When he got up from the couch and started yelling at Diaz, she said she first pointed the gun at him to scare him, but the gun went off. After she shot Wakeham the first time, she said he kept screaming and advancing toward her. She told police he fell after she shot him a second time.

Diaz had previously obtained an order of protection against Wakeham on June 29, but had it quashed on Sept. 29, according to police.

After a search warrant was executed at the residence, officers discovered evidence of a disturbance. However, officers reported it was inconsistent with the violence that Diaz described.

Diaz did present minor injuries consisting of an abrasion to her left arm, two scratch marks on her upper right arm, and a very small scratch on her left knee cap.
