CORPUS CHRISTI, Texas — Erin Dunn, the 28-year-old woman found dead at the Sandcastle Apartments on Monday, was the victim of a domestic crime, according to the Corpus Christi Police Department arrest report.
Moses Sandoval, who identified himself as Dunn's boyfriend to police, said he killed Dunn after an argument in which both Sandoval and Dunn admitted being unfaithful to one another.
Police were called after the 30-year-old Sandoval contacted a female friend, telling her he had choked Dunn and was unsure if she was breathing.
The report states the friend went to the apartment, while still on the phone with emergency services. After talking to Sandoval, the friend told emergency services Dunn was not breathing.
When officers arrived at the apartment complex, they found Sandoval and the woman who called police in the parking lot. When officers asked what happened, Sandoval told them his girlfriend was dead.
"I did it," he said, according to the report.
Officers handcuffed Sandoval and took him to the police station to be interviewed. The woman also was detained.
Sandoval is charged with murder.
Texas Department of Public Safety Public Information Officer Sgt. Nathan Brandley confirmed to KRIS 6 News on Wednesday evening that Dunn was an employee in the DPS' crime lab.
