A mother at the center of an abduction and child abuse case in the District has been arrested on a warrant charging her with theft and unauthorized use of a vehicle, according to police and court documents. Mikisha Funderburk, 27, is being detained in the District, where she was arrested, pending extradition to Montgomery County. D.C. police said officials are investigating the alleged abduction from Children's National Medical Center last Thursday. As part of that case, police said, they're also investigating allegations of child abuse. Rockville police Maj. Michael English said the charges against Funderburk are related to a car she used the day her children disappeared from the hospital. Police said a babysitter for Funderburk's boys, 5 and 10, contacted the D.C. Child and Family Services Agency to report suspected abuse. A social worker took the children to the hospital to be evaluated. Hospital officials said Funderburk was waiting for them in the lobby, distracted the social worker and ran off with her children. Police said they found the boys unharmed in a Rockville apartment. Man arrested in Capitol Hill standoff A nearly 12-hour standoff between D.C. police and a man they were trying to arrest near Capitol Hill's Lincoln Park ended Wednesday with a peaceful surrender, authorities said. Police said David Joseph Robertson, 25, of Southeast Washington was wanted on a warrant charging him with failing to appear for an Aug. 1 court hearing on a charge that he assaulted a police officer in April. The situation began about 10 p.m. Tuesday and drew dozens of police officers and heavily armed members of the tactical squad to the 1300 block of East Capitol Street, closing traffic on several other roads and forcing commuters to seek alternate routes. Police said that when they tried to deliver the warrant, Robertson refused to open the door to his apartment and barricaded himself inside. Officer Araz Alali, a police spokesman, said a woman inside the apartment with Robertson was briefly held against her will. Alali said the woman escaped during the standoff. Hostage negotiators were called to the scene. Alali said Robertson surrendered about 9 a.m. According to court records, the assault charge against Robertson stems from an April 26 incident after police stopped him after seeing him riding a bicycle without a front headlight through Lincoln Park. Trishula Patel and Peter Hermann Heroin overdoses up in Montgomery At least seven people have died of heroin overdoses in Montgomery County since March, a marked increase over previous years, police said Wednesday. The deaths have occurred throughout the county, and officials did not cite a reason. "This recent spike in deaths attributed to heroin is particularly alarming," Capt. Marcus Jones, head of the major-crimes division, said in a statement. From 2010 to last year, Montgomery recorded a total of seven heroin overdose deaths, authorities said. The recent victims have ranged from 19 to 45 years old. Six of the seven deaths have occurred since June. Authorities have seized an increased amount of heroin in the county, Capt. Nancy Demme said. Demme said other area jurisdictions also are seeing an increase in heroin activity. Dan Morse State officials seek dismissal from suit Virginia Gov. Robert F. McDonnell (R) and Attorney General Ken Cuccinelli II (R) have asked to be dismissed from a federal lawsuit that seeks to challenge the state's same-sex marriage ban, court records show. In a filing last week, Virginia Solicitor General E. Duncan Getchell Jr. argued that McDonnell and Cuccinelli have no "special relationship with the laws of marital eligibility" and thus enjoyed the protections of "sovereign immunity," which generally prohibits states from being sued in federal court. A Norfolk couple had sued McDonnell and Cuccinelli after they were rejected when applying for a marriage license. Getchell wrote in his filing that although a federal court can issue injunctions against state officials to prevent violations of federal law, those officials must have a "special relationship" with whatever is being challenged. In this case, he wrote, "neither the governor nor the attorney general have any proximity to, responsibility for, or a special relationship with the laws of marital eligibility."
