For weeks, the headlines have been full of investigations of top District government officials. Much of the investigating has been done by three men in the government, and their findings have become very public, indeed. But who are the investigators themselves? The District Weekly has prepared profiles of the three who have been involved in the investigations of Mayor Washington and human resources director Joseph P. Yeldell. The following is the second in a series.

"This job," says Carl McIntyre , "is a lonesome job. Damn lonesome."

Let us count the ways and whys.

First and foremost, McIntyre is the city's Dr. Bad News. When he calls on a District government official, it is not for tea. It may in fact be the start of a trip to jail.

Second, McIntyre does not socialize with the upper crust of city officialdom, as his status and salary ($39,600 a year) would permit. "You never know who you'll be investigating tomorrow," he explains.

Third, McIntyre must perform his investigations with a staff of four and a budget for the current fiscal year of only $158,900. As a result, his work often goes unfinished.Besides, he is often assigned rush projects, such as his recent inquiries involving Mayor Walter Washington and Joseph P. Yeldell.

What is his work? Carl McIntyre is director of the city government's office of campaign finance. his job is to assure that the city's employees and officials, elected or not, obey financial disclosure laws and avoid conflicts of interest.

It will not amaze the more cynical students of the District government to learn that McIntyre has more work than he can handle. What may be amazing is that McIntyre, who filed "reports" on 852 D.C. government officials and candidates for office in 1976, has been accused of $99[WORD ILLEGIBLE] out unfair treatment.

"My view is that when you're dealing with the rights of others, where you literally have the power to destroy them, that is not a job for ego-tripping," McIntyre said.

"I wasn't a gung-ho prosecutor and I'm not a gung-ho investigator. My responsibility is to try and strike some balance of reasonableness."

And thoroughness.Although few of the cases McIntyre prepares end up as criminal prosecutions, McIntyre, a former prosecutor, says he readies them as if they might.

The cases can be one of four types. A candidate for public office does not file financial disclosure statements; a lobbyist does not register and reveal the source of his funds; a matter of the City Council uses his or her neighborhood office for political purposes; any District government employees becomes involved in a conflict on interest.

In addition to candidated, al D.C. officials who earn more than $29,818 a year, and all officials who have authority to award contracts, muct comply with financial disclosure and conflict-of-interest laws.

Policing these laws and the approximately 2,100 employees and candidates they affect was not done in the District until 1974, the year the present system of limited home rule was enacted by Congress.

McIntyre was nominated by Mayor Walter E. Washington and confirmed by the Senate the same year.

His powers, defined by Congress, include the right to subpoena people and documents, and the right to make recommendations about his investigations. However, McIntyre and his office functions as an arm of the board of elections and ethics. The board makes any final decision to take action against offenders.

McIntyre's relationship with the board has bot been without its rumpled egos and ruffled feathers. "The board is very, should I say, media-orientated," McIntyre said. "I guess that's the kindest way I can put it. As an investigator, I'm just the opposite."

What he means is that neither his investigations now his reports are available to the public. That is "by policy, mine," not by law, McIntyre said.

The board of elections has at times passed information to the press while a McIntyre investigation was still under way, McIntyre said. That violated the privacy of the people involved, and may have spoiled possible criminal prosecutions, McIntyre said.

Much of McIntyre own experience is with civil prosecutions. He spent eight years as a staff attorney with D.C. corporation counsel, the last two as chief of law enforcement, before taking his present job.

McIntyre, 55, was born in Oak Grove, La. He grew up there and in Little Rock, Ark., where he graduated from Philander Smith College. He holds a law degree from Howard University. He is married and has two children - a 22 year-old daughter attending law school at Georgetown University and 18-year-old son attending Indiana University.

McIntyre got his present job because "I did such a good job (with the corporation counsel) that the mayor couldn't help but know about me." He said he would not call himself a friend of the mayor's, although the two men have known each other for many years.

Despite a two-month backlog and what he calls "killing" workload, McIntyre insisted that Washington, "compared to most states and cities, has one of the cleanest governments there is."

He conceded that polics almost always brings abuses, but he said many of those he handles are relatively minor. "We get a lot of losers for political office who don't file (financial disclosure) statements," McIntyre said. "You know, after you lose, you just don't give a darn."

Indeed, McIntyre said, the overwhelming majority of his cases involve the failure to file one statement or another. Only two of his 1976 cases were referred for criminal prosecution.

Despite his wish to avoid the limelight, MCIntyre has often been in the news the last two months because of two investigations he is conducting: One of alleged over-spending by Mayor Washington in his last campaign, and one of Joseph P. Yeldell's personnel pratices while director of the department of human resources.

"I know Joe Yeldell. I'd love to see him come out of his thing," McIntyre said. "But I'm not going to try to block a prosecution." McIntyre had no comment on his investigation of the mayor.

His abiding wish, McIntyre said, is for enough staff to do his job properly. A proposal to add two investigators and one auditor to his office is now before the City Council. Meanwhile, I'm doing a better job than I should be doing," McIntyre said. I'm pounding the pavement myself, and that was never intended.

But, he added, it's like anything else. The more pressure, the more you do. That's politics."
