A man accused of shooting an off-duty Clark County corrections officer in a conspiracy over a custody dispute has been extradited back to Las Vegas.

Agustin Victor Ramirez, 51, briefly appeared in front of Las Vegas Justice of the Peace Eric Goodman on Monday morning where bail for Ramirez was affirmed at $1 million.

Ramirez is accused of shooting officer Blane Dereis in Las Vegas on Sept. 21 as part of a plot with his sister, Guadalupe Ramirez, 48, of Las Vegas.

A Metropolitan Police Department arrest report for the siblings states Guadalupe Ramirez and Dereis are involved in a custody dispute over their 3-year-old daughter.

Police said in the arrest report that Dereis was walking out of a business with his girlfriend, Tanya Binko, and her 13-year-old son in the 7600 block of West Cheyenne Avenue at 8:43 p.m. when a man on a black electric bike rode past Dereis, then shot him. The officer was taken to a local hospital with a gunshot wound to the abdomen. He underwent surgery and his condition was stabilized.

As police investigated the shooting, they learned of the child custody dispute and of allegations that Guadalupe Ramirez was harassing Dereis’ girlfriend. Guadalupe Ramirez had obtained a restraining order against Dereis, which was dissolved. Dereis’ girlfriend then pursued a restraining order against Guadalupe Ramirez.

“She said Guadalupe used several ‘fake’ social media accounts over the last year to contact her and make threats towards her,” police said.

The custody dispute was so contentious that child exchanges were carried out between Dereis and Guadalupe Ramirez at a North Las Vegas police substation.

Agustin Ramirez is a convicted felon with prior arrests for being a participant in a criminal street gang, burglary and robbery. He was also arrested in North Las Vegas in May on suspicion of prohibited person possessing a firearm.

The gunman, police said, arrived in the parking lot on Cheyenne about 30 minutes prior to the shooting and appeared to be targeting Dereis.

Police said video surveillance from near Guadalupe Ramirez’s home showed Agustin Ramirez wearing clothes similar to the gunman’s in the hours before the shooting. Automated license plate readers also placed Agustin Ramirez in a vehicle that was spotted near the shooting scene.

A witness told police Agustin had an electric bicycle and a helmet similar to the one worn by the gunman.

The Ramirez siblings are each charged with conspiracy to commit murder, three counts of attempted murder and five counts of discharging a gun into an occupied structure or vehicle. A preliminary hearing for Guadalupe Ramirez is scheduled for Tuesday. Agustin Ramirez’s next court appearance is scheduled for Oct. 26.
