Allegheny County district attorney Stephen A. Zappala Jr. and leaders of the Citizen Police Review Board -- in separate requests -- said they want more information about the death of Ka'Sandra Wade and the disconnected 911 call placed from her home the night before she was found shot to death.

Two Zone 5 police officers -- Louis R. Schweitzer and Lance P. Hoyson -- went to Ms. Wade's house on New Year's Eve after a 911 dispatcher said a woman called from 528 Lowell St., "gave her address, was calm at first, then there was a commotion in the background and the line disconnected," the Pittsburgh Post-Gazette has reported.

When the officers arrived at the multiunit dwelling at 10:51 p.m., they talked to the man police identified later as Mr. Brown.

Speaking to the officers through a window, he told them there was no problem. Mr. Brown did not let the officers in.

Records indicate that the dispatch center tried to call Ms. Wade back, but the call went straight to voicemail.

After 10 minutes, the officers left at 11:01 p.m.

"There are a number of questions that need to be answered concerning the death of Ka'Sandra Wade and what information was communicated regarding the call placed to 911," Mr. Zappala said today in an emailed statement. "I am not going to comment any further until reviewing a transcript of the 911 call in question as well as any history of domestic violence that may have been present between Wade and Anthony Brown."

Elizabeth Pittinger, executive director of the Citizen Police Review Board, also said she will present information about the case at the board's Jan. 22 meeting.

The board will look into whether what transpired before Ms. Wade's death is related to policy or procedural issues in the department.

Based on their findings, the board could make recommendations to the city.

"It spiraled into a situation that was just overwhelming in its outcome," Ms. Pittinger said. "And how did that happen?"
