Police contend Manna went on a two-state shooting rampage on Monday night as he searched for his wife, Barbara, who left him last summer and filed for divorce in September.
Linda Delauter, 53, of Wolfsville, Md., who was fatally wounded, and Linda Grossnickle, 44, of Wolfsville, who was shot at but not injured, were friends of Barbara Manna who may have sheltered her after she left her husband, police said.
The wife of Richard Sanchez, the man Manna is accused of shooting in Pennsylvania, alleged that Manna had threatened to kill her husband several times, the most recent time being just hours before the shooting, according to court documents.
Candace Sanchez, 43, told Washington Township Police that Manna had displayed a handgun while making the threat Monday afternoon, court documents said.
Richard Sanchez, 48, was shot four times at about 10:45 p.m. Monday after an intruder smashed a glass door with a piece of firewood and fired at least five shots at him from a .45-caliber handgun, police said. He remained in serious condition Thursday in Washington County Hospital with wounds to the neck, chest, groin and ankle.
Shortly after his arrest early Tuesday, Manna told a Maryland State Trooper that he shot Richard Sanchez and Delauter and shot at Grossnickle, court records allege.
Ralph Manna told the trooper that he was upset that Candace Sanchez had moved back in with her husband at the couple's 10984 Gehr Road home, according to court records.
Washington Township Police Chief Kurt Braun said authorities believe that Ralph Manna and Candace Sanchez had had a romantic relationship.
Candace Sanchez said Thursday afternoon that she could not comment on whether she had a relationship with Manna, or about the threats alleged in the court documents. She referred questions to her attorney, Charles Ganley, who did not return phone calls to his office or home Thursday.
Sanchez had said in earlier interviews that she had not seen Manna for two or three months before the shooting. She has said that she and her husband occasionally had dinner with Barbara and Ralph Manna. The couples met as private pilots at Washington County Regional Airport, she said.
Following the shooting at the Sanchez home, a man fired several shots at Grossnickle through the door of her home in the 12600 block of Wolfsville Road at about 11 p.m.
Shortly after that, Delauter was shot in the chest and killed after she answered a knock on her front door in the 12000 block of Wolfsville Road.
Manna was arrested at 12:06 a.m. Tuesday when police found him in his Geo Prizm stopped on the shoulder of Interstate 70 near Ridge Road between Myersville and Frederick, police said. A .45-caliber handgun consistent with the shells found in the Sanchez home was found in Manna's vehicle, police said.
