After managing the day-to-day operations of the Baltimore Police Department for more than a decade, Deputy Commissioner Ronald J. Mullen is retiring from the department's No. 2 post to take charge of the Johns Hopkins University police department.
University officials confirmed yesterday that they have reached an agreement with Deputy Mullen, who will leave the Baltimore department in mid-July to head the 40-member Hopkins department on the Homewood campus.
The departure of Deputy Mullen, who has controlled the department's patrol and criminal investigation divisions for the last four police commissioners, marks a number of trends in the Baltimore department, which is undergoing a major reorganization.
Police spokesman Sam Ringgold said yesterday that Mr. Mullen would not be making any comment, adding that the department had scheduled an announcement for today.
A Baltimore officer since 1960, Deputy Mullen is one of the last proteges of the late Donald Pomerleau, who arrived in 1966 to recast a corrupt and inefficient department in his own image and lead that department into the early 1980s.
A cautious, taciturn man who always managed a low profile, Deputy Mullen rose through the ranks to serve as Commissioner Pomerleau's right-hand man during that era, inheriting day-to-day control of most essential police functions even after Mr. Pomerleau's retirement.
As a result, it was often Ronald Mullen rather than the police commissioners who shaped the daily operations and policies of the Baltimore department. Mr. Mullen's administrative safeguards and unswerving caution kept the force generally free of corruption and scandal, but critics argued that it also inhibited aggressive police work.
"No matter what you did or didn't do, you knew you'd eventually have to answer to R.J.," said one city police commander, who asked not to be identified. "He's the guy in this department that has his hand on everything."
But after arriving at the department's No. 2 spot, Deputy Mullen, who is white, was repeatedly denied the office of police commissioner as candidates leapfrogged over him.
