A Robstown man is behind bars after police found more than 40 grams of cocaine and a loaded handgun in his residence.

Police, acting off an anonymous tip, executed a search warrant May 8 at the residence of Ruben Pena Jr., 39, on the 300 block of North Fifth Street.

Pena was in the backyard when officers arrived but did not put up any resistance to the search, police said. Once inside, police found drugs and paraphernalia scattered throughout the residence.

About 42 grams of cocaine, with an estimated street value of $2,000, was seized, along with a small amount of marijuana. Police also found a scale and small bags that appeared to be meant for distributing the cocaine to potential buyers.

A loaded 9 mm handgun, and a wooden club, was also found in a drawer in Pena's bedroom, which he said he bought on the streets, along with two cases of bullets for the weapon.

"It's a good thing he was outside when we got there," said Police Chief Johnny Brown. "Otherwise there could have been a shoot-out."

Pena is a felon, having been previously convicted of assault and felony driving while intoxicated. In addition, police are investigating the possibility that the suspect is involved in gang activity.

"At this time, officers from the Robstown Police Department Gang Unit are working on confirming Pena as a gang member (Mexican Mafia)," Brown said.

Pena was transported to the Nueces County Jail on one count of manufacturing with intent to deliver, a first-degree felony, and one count of convicted felon in possession of a firearm, a second-degree felony. Jail officials said he also has four outstanding warrants. Pena is being held on $8,500 bond.
