On a day when condolences continued to pour in from around the country to honor three slain city police officers, emotions of a much different sort were on display in front of the house where the shootings occurred.

Relatives of Richard Poplawski, the man accused of ambushing and killing three police officers, alternately accused police of beating Mr. Poplawski, stealing cash from his house and refusing to let them back in the home.

City police did not respond to several messages requesting comment on the accusations.

An attorney released a statement from three family members this afternoon saying their public statements arose from confusion, shock and grief and that no additional comments would be forthcoming.

The family's anger was apparent on Monday, outside the home on Fairfield Street, as employees from the Pittsburgh public works department removed a piece of concrete walkway where one of the city officers died on Saturday.

Catherine Scott, the grandmother of the suspect, shouted at police after she arrived on Fairfield Street in Stanton Heights yesterday afternoon, hoping to get her purse from inside the house. She accused police of stealing money from her home.

"Your Pittsburgh Police officers stole my whole wallet," Ms. Scott shouted at officers and detectives after they retrieved her purse. "It had $3,020 cash, and it had all the checks that need to be cashed.

"The whole wallet is gone. My driver's license. My credit cards. They took my whole wallet."

Ms. Scott, who lived during the week at the home and in Greensburg on the weekends, then got into her white Chevy Lumina and sped off, going through a stop sign at the intersection of Fairfield and Antoinette streets.

Later, her sister, Debbie Devine, who is Mr. Poplawski's great aunt, said family members believe that police beat Mr. Poplawski after he was taken into custody.

"They beat him, and they cut his face," Ms. Devine said. "We haven't been able to see him or talk to him or nothing."

She did not explain how family members were able to find out what had happened to Mr. Poplawski after he had been taken into custody.

She said that the family called city police, the mayor's office and the sheriff's office yesterday to complain about his treatment, but at each turn, the person on the other end hung up on them.

She also complained that the family has been unable to re-enter their home since the shootings.

"They have jobs. They can't get their uniforms," said Debbie Devine, Mr. Poplawski's great aunt. "They can't get nothing."

Mr. Poplawski's mother, Margaret, who was in the home throughout Saturday's stand-off and made the initial 911 call about her son, shouted in the background throughout the conversation with Ms. Devine.

"Are they gonna protect my son from abuse because he shot a cop?"

The family at one point said it planned to hold a news conference Friday to give its side of the story.

"They want to give respect to the police officers' families," Ms. Devine said. "We do feel really badly about it, but we can't do nothing about it."

Yesterday, at the scene, public works employees were left to pry, pull and use a concrete-cutting saw to remove a portion of the home's walkway. The effort took more than an hour.

The slab is expected to be used as evidence in the case against Mr. Poplawski.

Police believe that after one officer collapsed outside the home on the stoop, Mr. Poplawski fired at least two more shots into his body. The slab may hold bullet fragments or impressions from those shots.

At one point, Sgt. Daniel Connolly, who was on the scene, took a sledgehammer from the city employees, and began pounding the concrete himself.

A neighbor said yesterday that she never had any problems with Mr. Poplawski, and in fact he had helped to shovel her snow after she had a baby and offered assistance in taking out her trash.

But she went on to say that Margaret Poplawski would often fight with Ms. Scott. Sometimes, the arguments were so bad that Ms. Poplawski would throw things out of the house, including a television and chair.

Yesterday, Ms. Poplawski would not answer questions about the situation. But her aunt, Ms. Devine, said the family was "baffled" by what happened.

"We are all remorseful. We know he did wrong," she said. "He shouldn't have done it."

This afternoon Margaret Poplawski, Catherine Scott and Debra Devine released the following statement through an attorney:

"Our confusion, shock and grief led us to make public statements when it would have been more appropriate to refrain. We are therefore declining to make further comment and ask members of the media to respect our privacy and make no further attempts to contact our family."
