Gallup Police Department’s narcotics and K9 teams netted 78 grams of heroin when they conducted a drug raid Oct. 6 at David Grijalva’s residence, 104 S. First Street, Apt. 6.

Grijalva, 63, was part of a three-month long investigation, in which during that time he allegedly  sold drugs to undercover narcotics agents.

GPD Capt. Rick White said the drugs confiscated were sent to the state’s Forensic Laboratories Bureau for testing to confirm the presence of heroin. When police receive confirmation, they’ll be able to charge Grijalva for possession of a controlled substance.

Meanwhile, he was arrested for trafficking drugs and is being held at the McKinley County Adult Detention Center on a $10,000 cash or surety bond.
