A jury Friday convicted a Colorado Springs man in a 2018 double-slaying in which two people were shot in the head and left in a burning car in a scheme to steal up to a pound of marijuana. The panel found Nashid Rayon Rivers guilty of multiple counts of first-degree murder in the drug-heist killings of Serena Garcia, 21, and Marcus Denton, 20, on the city’s southwest side. Rivers also was convicted of aggravated robbery, tampering with human bodies and other counts. Fourth Judicial District Judge Frances Johnson moved directly to sentencing, imposing an automatic penalty of life in prison without parole.
