Police allege Cecilio Sanchez Lopez shot 19-year-old Roman Valenciano after a traffic confrontation on San Mateo Boulevard.
ALBUQUERQUE, N.M. — A 31-year-old man will remain jailed while awaiting trial on charges that he fatally shot a 19-year-old driver during an alleged road-rage confrontation on a busy Albuquerque street.
Cecilio Sanchez Lopez is accused of killing Roman Valenciano on March 26 as the teenager drove to pick up his mother after work. Lopez faces an open count of murder, shooting at or from a motor vehicle resulting in death, tampering with evidence and possession of a firearm by a felon. A judge ordered him held before trial after prosecutors argued that releasing him would pose a danger to the community.
The shooting occurred shortly before 2 p.m. near San Mateo Boulevard and Phoenix Road in northeast Albuquerque. According to police accounts of the criminal complaint, surveillance video showed a silver Ford Mustang make a U-turn and enter the path of Valenciano’s gray Nissan Sentra. Investigators allege the Mustang repeatedly slowed or stopped in front of the Sentra as the vehicles traveled south.
Police said the Mustang eventually pulled beside Valenciano’s car and gunfire followed. A gunshot-detection system recorded two rounds at about 1:48 p.m., according to reports citing the complaint. One bullet struck Valenciano, and another passed through a rear window of the Sentra. His vehicle slowed and stopped in traffic near a restaurant on San Mateo Boulevard.
Officers found Valenciano unresponsive in the driver’s seat, and he was pronounced dead at the scene. Police have characterized the confrontation as road rage, although the complete sequence leading to the shooting remains part of the pending criminal case. The charges against Lopez are allegations, and he is presumed innocent unless proven guilty.
Investigators used surveillance recordings and license plate reader information to trace the Mustang, police said. Detectives also alleged that cellphone records placed Lopez’s device near the shooting scene. Officers arrested him the following day at a North Valley home with assistance from a SWAT team.
Police said the Mustang was silver when cameras recorded it around the time of the shooting but was later found painted black. Investigators said several identifying features remained unchanged, including its wheels, rear spoiler, window louvers and license plate. Authorities allege the change in color was part of an effort to conceal evidence, a claim reflected in the tampering charge.
Valenciano’s mother, Deborah Valenciano, told local news outlets that her son was driving to collect her when he was killed. She said a relative recognized his car in television coverage and that she went to the scene, where a detective told her that her son had died.
She described Roman as someone who enjoyed cooking, art, music, animation and video games. She also said he helped support his family and encouraged those close to him. His death came after the family had already lost his father to cancer the previous year, she said.
Records cited during coverage of Lopez’s detention proceedings showed that he had previously been convicted in a separate homicide committed when he was a juvenile. Prosecutors cited his record, probation status and the new allegations when asking the court to keep him jailed. His defense opposed an additional detention order, noting that he was already being held over an alleged probation violation.
The prior conviction does not establish guilt in Valenciano’s death. The current case must be decided on its own evidence, and prosecutors will be required to prove the charges beyond a reasonable doubt. No trial date was identified in the reports reviewed for this article.
Lopez remains in custody as the murder case proceeds in New Mexico District Court. Further hearings, evidence disclosures and any formal plea will determine the next steps in the prosecution.
