Prince George's County Executive Parris Glendening is expected to seek the County Council's authorization to hire dozens of police recruits, pushing the county force to more than 1,000 officers, when he announces his plan today to "dry up" the expanding drug market in the county.

Glendening will announce "a series of initiatives to combat illegal drugs," according to a statement released by his office. His plan is expected to include provisions for as many as 100 new police officers and guards at the county's correctional center.

"It will involve a lot of elements of county government and even beyond county government," said Glendening spokesman Tim Ayers. "It'll affect the entire criminal justice system," Ayers said.

The cost of Glendening's initiative is expected to be several million dollars, but County Budget Director Major Riddick would not yet provide specific figures.

"Parris is looking to give special emphasis because of his concern with the drug problem that has been occurring at some of the larger apartment complexes in the county," Riddick said.

The announcement comes at a time when "we have noticed, as have other jurisdictions, an alarming increase in drug-related crime," said Cpl. Bruce D. Gentile, a police spokesman.

A record 96 homicides were committed in Prince George's County last year, an 84.6 percent increase over the 52 recorded in 1986. Gentile said 38 percent of last year's slayings were drug-related. Additional crime figures are not available because the county's computer has not been working since early last year.

The county spends about $103 million -- 13.9 percent of its $740 million fiscal 1988 budget -- on public safety and criminal and civil justice. Public safety alone accounts for $79.3 million, which includes funds that were added last year for 30 new police officers and 55 other emergency operators, firefighters and other public safety positions.

The budget increase that will go to public safety "will probably {be} a little higher" than the 5 percent increase that Glendening is expected to propose for the school system budget for fiscal 1989, Riddick said. Some of the funding for the program, however, is expected to come from the federal government.

Most of the additional law enforcement slots are expected to go to the police force. Last month, the National Institute of Corrections released an audit that recommended that at least 40 guards be hired for the county jail.

That recommendation represents ideal staffing, said jail spokeswoman Christy Merenda, but "the county executive's response will be what we can afford at this time."

Merenda said the $43 million state-of-the-art prison, which has a rated capacity of 596 inmates, was holding 846 prisoners yesterday. A crackdown on drug dealers and drug buyers could swell the prison population.

However, Merenda said that the prison was designed for double bunking and could easily accommodate almost 1,200 inmates, although additional staffing would be necessary, she said.

Three weeks ago, Prince George's State's Attorney Alex Williams formed a special seven-member team that prosecutes only drug cases. Yesterday, his spokeswoman, Alexis Revis, said the office would target repeat drug offenders and would "try our best to get the maximum sentences for drug offenders."
