Victor D. Lassiter of Sterling was taken into custody without incident early Monday, according to Liz Mills, spokeswoman for the sheriff's office. The arrest followed a search warrant executed at Lassiter's home on Gable Square in Sterling, she said.

Lassiter is charged with robbery, malicious wounding and weapons charges stemming from the shooting, which took place about 4:40 p.m. Sunday at a residence in the CountrySide community in Sterling, according to the sheriff's office.

When deputies responded, they found the victim suffering from multiple gunshot wounds, Mills said.

The sheriff's office continued to search for a possible second suspect in the incident, Mills said. Two suspects were believed to have fled the scene before law enforcement arrived, according to authorities.

Investigators think that the suspects were known to the victim, who was apparently targeted, authorities said.

The sheriff’s office said in a statement that the shooting “does not appear to be a random act.”

The victim, whose identity was not released, was airlifted from the scene to a hospital where he was being treated for his wounds, according to the sheriff’s office. Authorities declined to provide further information about his condition.
