Six people were slain in Baltimore from Wednesday through yesterday, bringing the number of homicides to 70 so far this year -- two more deaths than had been recorded at the same time in 1992.
There were 335 homicides last year, the most in Baltimore history.
The most recent victim was Sister MaryAnn Glinka, a 50-year-old nun, who was slain early yesterday at the Franciscan Sisters of Baltimore Motherhouse Community in the 3700 block of Ellerslie Ave.
An arrest warrant was issued late last night for a suspect, Melvin L. Jones, 34, whose last known address was the 1600 block of E. 32nd St., police said. He was charged with first-degree murder and burglary.
At least six detectives were assigned to the nun's slaying, which was declared a "top priority" case by police officials.
Asked about the spate of slayings yesterday, Police Commissioner Edward V. Woods described them as "man's inhumanity to man."
"I am very concerned with the random acts of violence that are occurring in our city," Mr. Woods added.
Among this week's slaying victims was Larry Eugene Wilson Jr., a 16-year-old junior at Polytechnic Institute whose cousin, Kenneth L. Blackwell, is a major in the city Police Department, relatives said.
Police said the youth was shot twice in the back about 10 p.m. Wednesday in the 4400 block of Moravia Road while walking to a store to pick up some clothing dye for his grandmother.
The victim's father, Larry Eugene Wilson Sr., said his son was a "good boy" who was an honor roll student at Polytechnic Institute and had hopes of attending Howard University in Washington.
Police said they knew of no motive or suspects in the slaying of young Wilson.
Sam Ringgold, a police spokesman, was also affected by one of this week's slayings. He was awakened Thursday morning by a homicide detective and told about the death of 74-year-old Jeromia B. O'Neal, who was the mother of a Channel 2 cameraman with whom Mr. Ringgold had worked when he was a newsman there.
"I was like . . . totally shocked," Mr. Ringgold said. "It really hit close to home."
Police believe robbery was the motive for the slaying of Mrs. O'Neal, whose bedroom had been ransacked.
About 10:30 a.m. Thursday, the body of Andre White, 18, of the 1400 block of Wilmer Court was found in the 500 block of Wilson St., police said. He had been shot in the chest.
Shortly before 11 p.m. Wednesday, two brothers from Trinidad, Rajesh Mangatoo, 22, and Kamal A. Mangatoo, 20, were found shot to death in their basement apartment in the 5200 block of Bowley's Lane, police said.
Although several ounces of marijuana were found in the apartment, police were uncertain if the slayings were drug-related.
