Larry P. Hallman, 28, was sentenced yesterday to two consecutive life terms in prison plus nine years for arson by a D.C. Superior Court judge who refused a defense request that he "leave some light at the end of a long and arduous tunnel."

Judge Nicholas S. Nunzio imposed the penalty for Hallman's part in the stabbing murders of Curtis Arrington, 23, and Lois Ann Davis, 16, in a public housing project at 1200 Delaware Ave. SW on Oct. 22, 1975. Following the murders, the apartment was set on fire.

Hallman was the third person sentenced in connection with the deaths. Earlier this month Eddie Wilson, 19, and Warren Peters, 20, both of whom pleaded guilty to these and other crimes, received prison terms ranging from a minimum of 28 years in prison to life in prison.

A fourth defendant, Raymond Paris, 18, was permitted to plead guilty to second-degree murder in return for his testimony against Hallman, in a trial that ended last month with Hallman's conviction.

At the time that Wilson and Peters pleaded guilty, Judge Nunzio indicated that he would limit the lower part of their terms to no more than 28 years. When he sentenced them, he said he regreted the limitation he placed on himslef. Under D.C. law, the minimum part of a sentence must be served before a prisoner becomes eligible for consideration for parole.

At yesterday's sentencing Stuart Stiller, Hallman's attorney, asked Nunzio to make it possible for his client to be considered for parole in 30 years.

But Nunzio came within a year of ordering the maximum permitted by law: 20 years to life on each of the murders count plus nine years (rather than the maximum of 10 years) for arson. For purposes of parole eligibility, this means that Hallman will not be eligible for consideration for 43 years.
