Mesa Police say they have arrested a man suspected of killing his girlfriend and living with her body for more than two months.
35-year-old Erik Grumpelt was charged Tuesday with one count of second-degree murder.
After receiving a tip from Grumpelt's father, officers went to the suspect's apartment Monday and discovered the body of 39-year-old Melinda Raya on a bedroom floor under several sheets.
Investigators say the body was in an advanced state of composition and surrounded by air fresheners.
"We were at the pool last week, we thought it was sewer... something sewer-y, we were saying something stinks something rotting but we didn't know what," recalls neighbor Samantha Banda.
Authorities allege on May 19, Grumpelt struck Raya repeatedly in the abdomen after learning she had cheated on him. When she became unresponsive, police say Grumpelt tried to revive her.
He then panicked and tried to hide her body.
The medical examiner's office will be performing an autopsy.
