Alex Madrid was convicted of murdering 14-year-old Claudia Lucero in 2013

More than a decade after the death of a 14-year-old Mesa girl, a man charged with murder was found guilty Wednesday in Maricopa County Superior Court.

After a 27-day trial, a jury found Alex Madrid guilty on all counts of murdering Claudia Lucero.

Claudia's body was discovered in a dumpster two miles from her family's home in December 2013.

Madrid had ended a relationship with Lucero's mother earlier that year, and prosecutors argued that he had access to the family's apartment and intended to sexually assault Claudia.
