Through the course of an extensive investigation multiple suspects were developed; and ten suspects were arrested in May of 2009. As those ten suspects were interviewed, detectives learned of an eleventh suspect known only as “Tremendo”. His true identity remained unknown for several months. He was described as a Hispanic male, approximately 17 years old, possibly residing in Washington, D.C., and having a tattoo of a “devil” on his shoulder. Montgomery County Police detectives worked with gang officers in Washington, D.C. to try to locate this remaining suspect.
On January 19, 2010, Metropolitan Police arrested a suspect with gang affiliation for attempted armed robbery who had a devil tattoo on his shoulder. He was also found to have a tattoo of “K Tremendo” on his stomach. Montgomery County police detectives were able to interview the suspect, and establish probable cause to obtain a warrant for his arrest. Yesterday, U. S. Marshals in New Braunsfel, Texas, just outside of San Antonio, located him and took him into custody.
Edgar Antonio Garcia-Zavala, AKA “Tremendo”, age 18, from the 3900 block of 14th Street in northwest Washington, D.C., is currently being held in Texas, awaiting an extradition hearing. Montgomery County Police have a warrant for him with the charges of first-degree murder, kidnapping, conspiracy to commit first-degree murder, and conspiracy to commit kidnapping.
Garcia-Zavala, a member of the 18th Street gang, was a passenger in one of two vehicles that drove to Malcolm King Park and participated in the stabbings that occurred in that park.
The previous suspects arrested, all members of or associated with the 18th Street gang, include: Daniel Abisail Zavala, Ysaud Flores, Silvia Martinez, Joel Yonathan Ventura Quintanilla, Edwin Antonio Lopez, David Antonio Lozano, Ana Idalia Abarca, Ana Villatoro, Joel Antonio Lovo-Reyes, and Francis Emerson Artiga-Cardoza.
The investigation revealed that Guzman-Saenz had left his home in Langley Park the evening of January 18, and walked to a metrobus stop in front of his residence with the intention of taking a bus to a friend’s house. Through the course of the investigation it was learned that Guzman-Saenz was forcibly abducted by five members/associates of the 18th Street gang. Guzman-Saenz was not an official member of the rival MS-13 gang, but associated with MS-13 gang members. Eighteenth Street gang members were driving around Langley Park that evening. The date, 18, was significant to them because of their gang name and they were planning to find a member of rival gang MS-13 to harm. When they spotted Guzman-Saenz at the bus stop they stopped and talked to him, posing as MS-13 gang members so that they could determine if he was affiliated with that gang. Whatever information Guzman-Saenz provided about MS-13, it caused the 18th Street gang members to forcibly grab him, and drive away with him. It is believed that the group arrived in Gaithersburg near 8:00 p.m., and that the murder occurred no later than 8:30 p.m. on January 18. Guzman-Saenz’ body was later found by a community member cleaning up the park the next morning. He had been stabbed multiple times, and his body left in the water at the edge of the creek.
With the arrest of Garcia-Zavala, detectives believe all of the suspects responsible for the murder of Dennys Guzman-Saenz have been identified and taken into custody.
