Julius Sylvester Bailey, 29, a District man described by some prosecutors and police as a "one-man crime wave," received three consecutive life sentences plus 340 years yesterday in Prince George's Circuit Court in several murder and kidnaping cases.

Bailey had been convicted in jury trials of one murder and two kidnapings and yesterday he pleaded guilty to another murder and an attempted murder. Judge Audrey Melbourne imposed the sentences for the crimes, all of which occurred during December 1983.

Several months ago Bailey was found guilty of kidnaping Jan Adams, a nurse, from a Georgetown office and forcing her, at gunpoint, to withdraw money from her bank machine and purchase clothing for him before she escaped. Bailey also was convicted of a similar kidnaping of James Taylor, 24, outside a convenience store in Montgomery County.

Last month a jury convicted Bailey of the brutal rape and murder of Anne Boggs, a 22-year-old Catholic University student. That jury decided against the death penalty in that case.

Yesterday Bailey pleaded guilty to attempted murder of Nettie Sue Meadows, a Calverton woman whom he shot during an attempted robbery outside her apartment. He also admitted killing Alexander Boateng, a cabdriver who was shot outside his Adelphi apartment.

Melbourne sentenced Bailey to consecutive life terms for the Boggs and Boateng murders, and the attempt on Meadows' life. He received an additional 340 years for the kidnapings and numerous other related charges. Prosecutor Robert Harvey said he expects Bailey to be in prison the rest of his life, because he is not eligible for parole consideration for about 100 years.

Adams, one of the kidnaping victims, said yesterday, "I'm satisfied with the sentence. I believe it is the maximum the judge could give him." But she added that she still feels threatened because no one can assure her that Bailey will never get out of prison.
