Rancho Viejo police are investigating the death of a woman identified as the daughter of Ray Marchan, the Cameron County attorney who committed suicide at South Padre Island early this year.

Rancho Viejo police responded to the La Jacaranda Apartments located on Santa Ana Ave., Tuesday afternoon and found 22-year-old, Devon Raye Marchan unconscious on her bed.

She was taken to Valley Baptist Medical Center where she was later pronounced dead.

An autopsy has been ordered to determine a cause of death but investigators believe she died from asphyxiation by strangulation.
