CORPUS CHRISTI, Texas (AP) — A South Texas man must serve 10 years in federal prison after being caught with about 700 packets of synthetic marijuana and several guns.

Prosecutors say 28-year-old Abel Martinez of Corpus Christi was sentenced Monday.

Martinez in September pleaded guilty to possessing with intent to distribute a synthetic cannabinoid and for being a felon in possession of a firearm.

Martinez was arrested in June. Officers seized an assault rifle, two loaded handguns, a stolen bullet-resistant vest and hundreds of packets of synthetic marijuana.

Authorities didn't immediately provide a criminal history for Martinez, who received concurrent 10-year prison terms for each conviction.
