Crackdown on the Monk Mobb follows a Halloween party spray of gunfire that killed a 24-year-old man and injured four of his friends.Early on, detectives suspected Monk Mobb members in the killing. But as they built their case, detectives gathered information that led to nearly a dozen arrests for other violent crimes – including shootings and robberies – and that could lead to more. What detectives hope will be the final blow came this week, when officials arrested eight suspects – six of them allegedly from the Monk Mobb, and one from TNA, an associated subset in the larger North Highlands Gangster Crips organization – in the Nov. 1 homicide."Monk Mobb and TNA have been problem gangs for us for a long time," said homicide Detective Angie Kirby. "Our goal not only was to solve this murder but take down the entire gang and eliminate this constant problem and threat to public safety."Detectives say they have arrested about a third of the still relatively small Monk Mobb crew. But they're confident, they say, that their efforts will be effective in "dismantling" the gang. And the pressure remains: Sheriff's gang detectives and FBI agents are continuing their push. More arrests are expected.The magnitude of the case and level of cooperation within the Sheriff's Department and with outside agencies is "virtually unheard of," said Detective Scott Swisher.The effort grew out of a Nov. 1 homicide on Rogue River Drive. Patrick Razaghzadeh, 24, was hosting a costume party at his home when the suspects crashed the gathering, detectives said. When an argument erupted about their behavior, one of the suspects unloaded a 9 mm handgun into the crowd.Razaghzadeh, dressed as an Oakland A's baseball player, took a bullet to his head and died in his rain-soaked backyard. Four of his friends suffered gunshot wounds.At the party, the gangsters had been throwing gang signs, causing trouble and trying to push drugs – working, Kirby said, as a "gang pack."That pack mentality continued as the assailants tried to cover up the identity of the trigger man, detectives said.Their loyalty, however, apparently went only so far. Some of the gang members eventually cooperated with authorities and fingered one another as being involved, detectives said.According to a criminal complaint filed by the Sacramento County District Attorney's Office, the accused are Corey Andre Carmicle, 22; Charles Steven Ferrell III, 21; Willie Cavil Harris IV, 19; Willie Earl Toliver, Jr., 22; two 18-year-old men who were 17 when the shooting occurred; and a 16-year-old boy who was 15. The Bee is not naming those suspects because they were juveniles at the time of the crimes.The suspects being held at the Sacramento County Main Jail were unavailable for interviews Thursday. Two remained in juvenile hall.Each of the suspects faces one count of murder and four counts of attempted murder, according to the complaint. They also face enhancements for allegedly committing the shooting with a handgun and on behalf of a street gang.The eighth suspect, Leighni Nikkol Hadl, 23, faces one felony count of conspiracy, according to the complaint.Razaghzadeh was the fourth Sacramento County resident to fall fatal victim to the Monk Mobb and TNA – which detectives describe as a "younger set" that includes siblings of Monk Mobb members – according to detectives from the Sheriff's Department and the city Police Department.Sheriff's detectives also allege that the two gangs are responsible for a dozen or more shootings and 70-plus robberies in 2008 alone. The spree has continued: When arrested this week, one of the unnamed 18-year-old suspects in the Rogue River case already was in custody, accused in a February shooting in North Highlands, Kirby said.Razaghzadeh's killing particularly concerned detectives because they saw it as an escalation in the gangs' violence: None of the victims was a gang member, and the alleged assailants were far out of their usual territory.During the investigation into Monk Mobb and TNA, detectives "had an opportunity to gain a whole lot of intelligence about how they operate, who they talk to, what they do and what kinds of crimes they're committing," Kirby said.That allowed them to arrest almost a dozen other gang members on suspicion of unrelated felonies and to seize drugs and weapons possessed by them, detectives said. They also collected information on a number of unsolved crimes, including homicides, though detectives declined to elaborate.In addition to any other arrests that might stem from that intelligence, detectives said it's possible they will make more arrests in the Rogue River case.For now, though, the arrests have Razaghzadeh's family on "cloud nine," said his mother, Trish O'Connor. "I think Pat can finally rest now," she said.Although the seven months since her son's death have been trying, O'Connor said she never gave up hope that detectives would make an arrest. Their regular updates kept her going, she said."They were just so persistent," O'Connor said. "I'm just so elated and thankful to them."Recently, Razaghzadeh's sister gave birth to a son and brought some joy into the family. His name: Ethan Patrick, after the uncle he'll never meet.
