WICHITA , Kansas -LRB- CNN -RRB- -- Kansas prosecutors have brought murder and assault charges against the man suspected of killing Wichita physician George Tiller , whose women 's clinic was a frequent target of protests against abortion . Scott Roeder , 51 , is being held on a first-degree murder charge and two counts of aggravated assault . Scott Roeder , 51 , is being held without bail on a first-degree murder charge and two counts of aggravated assault stemming from Tiller 's shooting death Sunday morning , Sedgwick County District Judge Ben Burgess said . Burgess set a preliminary hearing in the case for June 16 . Police have not disclosed a possible motive in Tiller 's killing , but associates said Roeder was a regular among the anti-abortion protesters who routinely gathered at his Wichita clinic , Women 's Health Care Services . Tiller , 67 , was one of the few U.S. doctors who performed late-term abortions , and he had survived one attempt on his life before being gunned down in his church Sunday morning . Prosecutors will not seek the death penalty `` under the facts and circumstances that are known at this time , '' District Attorney Nola Foulston said . Watch the district attorney explain the charges '' Kansas state law allows the death penalty only in certain circumstances , such as multiple killings , contract killings , the deaths of police officers or jailers , or a slaying that takes place during a sexual assault . Roeder was in the county jail during his brief initial court appearance and appeared in court via video . He requested a court-appointed lawyer during the hearing , during which he was dressed in maroon jail coveralls and appeared to fidget . Watch scenes from court Tuesday '' Burgess ordered Roeder to have no contact with witnesses or Tiller 's family . Since Tiller 's death , supporters have left a few bouquets of flowers outside his clinic . The architecture of the low-slung , windowless concrete building -- which is fenced off , monitored by cameras and separated from buildings behind it by a moat-like ditch -- reflected the threats he faced for nearly two decades . In a statement issued Tuesday , Tiller 's family said they hope his `` valuable work '' will go on , `` but there have been no final decisions made about the long-term plans for the medical practice . '' `` There is currently no plan to immediately reopen the clinic and no patients are being scheduled at this time . The Tiller family 's focus , of course , is to determine what is in the best interests of the employees and the patients , '' the statement read . Dr. Leroy Carhart , a Nebraska physician who also practices at Tiller 's clinic , said at his suburban Omaha office that he left a Monday meeting in Wichita with the belief that the practice would reopen `` in the very near future . '' But he said , `` At the present time , there 's no known future . '' Carhart was the plaintiff who challenged a federal ban on a type of late-term procedure that opponents labeled `` partial-birth '' abortion . The Supreme Court upheld the ban in 2006 . Tiller practiced medicine for nearly 40 years . Most of his patients were grappling with pregnancies that were `` fatally or catastrophically complicated by medical problems , '' Dr. Warren Hern , a Colorado physician and a friend , said on CNN 's `` Anderson Cooper 360 . '' `` The many women who come for late abortions , in fact , have desperate circumstances with a desired pregnancy , '' he said . `` They want to have a baby , not an abortion . '' But Tiller 's practice made Wichita a flashpoint in the controversy over abortion , which opponents routinely decry as the killing of unborn children . Most anti-abortion leaders quickly condemned Tiller 's killing and disavowed Roeder . The National Right to Life Committee , the largest anti-abortion organization in the United States , said it `` unequivocally condemns '' violence . And Wichita-based Operation Rescue said Roeder never was `` a member , contributor , or volunteer . '' `` Operation Rescue has diligently and successfully worked for years through peaceful , legal means , and through the proper channels to see to it that abortionists around the nation are brought to justice . Without due process , there can be no justice , '' it said . But Hern called those disavowals `` hypocritical nonsense . '' `` This is the result of 35 years of anti-abortion harassment and terrorism and hate speech and rhetoric and harsh names and exploitation of the abortion issue as a political issue to get power , '' said Hern , who runs an abortion clinic in Boulder , outside Denver . `` And this is the inevitable result of this kind of hateful behavior by the anti-abortion movement . '' Carhart blasted abortion opponents who resort to violence `` and those who support and incite these violent acts . '' He declined to name names but urged the estimated 46 million women who have received abortions and their supporters to demand that government officials `` enforce the laws on the books that protect us from hate crimes . '' `` And if these officials do n't openly respect your right to choose abortion , you have the power to vote them out of office , '' he said .
