A man arrested in Prince George's County last month for allegedly posing as a physician, possessed documents enabling him to assume the identities of 32 different people, including doctors, lawyers and educators, according to Baltimore law enforcement authorities.

Officials in the Baltimore state's attorney's office said that the identification documents belonged to real people living in several different states.

The man was so mysterious, according to prosecutors, that they aren't certain that his wife knows his true identity. Baltimore Det. Charles Rothrock said that they have now "identified" the suspect as William Junis Lott, 33, a native of Harrisburg, Pa.

Lott was arrested by Maryland State Police April 22 as he sat in his wife's car outside his Hillcrest Heights. He was then said to be Robert E. Lee Pugh Jr.

Lott's attorney said he didn't know that Lott was his client's real name until the state's investigators uncovered it.

Lott thus far has been indicted on four counts of false pretense. The charge involves using the name of another person with the intent to defraud. It is not a crime in Maryland simply to use the name of another person, Rothrock said.

Shortly after his arrest he was indicted under one of his assumed names for impersonating a physician and on 34 counts of dispensing a drug without a license in connection with his working at the state penitentiary.

Rothrock said prosecutors will seek indictments against Lott under all 19 of the names they think he's used in the last eight years in Maryland and the District of Columbia.

Investigators have pieced together some details of the man's activities in Baltimore.

Prosecutors have determined so far that at different times and with different credentials from 1969 to 1974, Lott worked for or sought jobs with the Baltimore City public schools, Morgan State University, Coppin State College, and the Community College of Baltimore.

City school officials confirmed that Lott under the name Leon Collier, was hired on probationary status as a full-time teacher and taught for two years in two junior high schools. He was dismissed in January, 1972, because he didn't "measure up to standards," the official said.

However, Lott then applied for and was accepted, again under the name Leon Collier, as a school system night school teacher, the official said.

Lott's last known job with the school system was in 1974 when he was hired under the name of Melvin Williams, Ph.D. for a planning specialist position in one of the schools district offices.

The official said Lott was abruptly dismissed in December, 1974, after an interview with then-Supt. Roland Patterson that was prompted by suspicious about his credentials.

Prosecutors also said that during 1972 Lott taught at Morgan State University, the Community College of Baltimore, and sought a teaching position at Coppin State College.

Morgan State officials said they were unable to find any record of a faculty member with the names Lott is said to have used then. Officials at the Community College of Baltimore said Lott, using the name Robert J. Cunningham, Ph.D., taught an introductory psychology course there during the spring of 1972.

Lott's alleged attempt to fool Coppin State College was unsuccessful however.

Dr. Leroy Fitzgerald, professor of education at Coppin State and dean of its graduate studies program in 1972, recalled that Lott, using the name Cunningham, came to him armed with glowing letters of recommendation from several Morgan State faculty members.

Fitzgerald, before hiring him, suggested he lead a graduate class discussion. "He gave a rambling discourse I couldn't make heads or tails of," Fitzgerald recalled. "It just wasn't impressive at all."

After the class a student who was a Baltimore public schools employee told Fitzgerald he recognized "Dr. Cunningham" as Leon Collier, the former school employee.

"Well, I asked Cunningham to come meet with me again," Dr. Fitzgerald said drily, "and I also invited the (public) schools' chief psychologist who knew what Collier looked like. (The Schools' psychologist) went up to Cunningham and said, 'don't I know you?' Cunningham exited from my office pretty quickly. He didn't come back."
