(FOX40.COM) — A woman was arrested in Citrus Heights on Monday in connection to a decade-long homicide investigation, according to the Citrus Heights Police Department.

In April 2013, Diego Lopez, 22, was brought to Mercy San Juan Hospital with breathing difficulties and coughing up blood, according to police.

Physicians found that his illness was caused by injections of non-medical-grade silicone that caused multiple organ failures, cardiac and his eventual death on May 7, 2013.

Detectives launched a homicide investigation following Lopez’s death and determined Alejandra Aguilera-Ortega, 49, was a suspect after learning she had been injecting Lopez for a fee without a medical license.

Aguilera-Ortega fled to an unknown location in Mexico as detectives were preparing to serve her with a homicide arrest warrant.

Recently detectives learned that she had returned to Citrus Heights and arrested her at an area apartment complex.
