On January 26, Osman Abdullahi was gunned down by D.C. Police after an altercation inside his unlicensed group home. The home, located at 830 7th Street NE, had no heat, very little food, and no supervision. Abdullahi wasn't taking his medication at the time. The home's manager Mark Spence has a long history with troubled group homes. We published a cover story on Spence's activities and Abdullahi this week.

Within a few days of the incident, Spence effectively shutdown his group home. The lights were turned off. The doors were locked. A mysterious notice to "correct" or "vacate" was placed on the door.

The Department of Consumer and Regulatory Affairs told me they have no record of posting such a notice on the door of 830 7th Street NE. The notice cited overcrowding as an issue. Spence had 30 days to correct the overcrowding problem or face some kind of fine or eviction. I saw the notice. The notice did not have DCRA letterhead or a name and phone number of an inspector who made the determination.

I asked Spence about the note. He told me the building's owner could have posted it. He added that he had cleared everyone out of the building. This is a clear violation of landlord-tenant regs. No one stopped Mr. Spence from ignoring the law.

The Office of the D.C. Long-Term Care Ombudsman Program has had frequent encounters with Spence’s work, dating to 1999, according to Jerry Kasunic, the office’s current director.

Today, Kasunic met with the Department of Mental Health. He had one question for the department: Where did the residents of 830 7th Street NE go?

The department's answer: We don't know.

In early November, D.C. police entered David Kerstetter's Logan Circle home and shot and killed him. Police say Mr. Kerstetter had a knife, that there was a struggle. The crime scene shows no evidence of a struggle. On January 26, Osman Abdullahi was shot and killed by D.C. police after they entered his unlicensed group home at 830 7th Street NE. He had a knife. He used a metal pole as a weapon. He allegedly tried to attack the police. Witnesses say he urged the police to kill him. Abdullahi is the subject of this week's cover story.

What did Kerstetter and Abdullahi have in common? They were both residents in crisis. Both suffered from mental illness. Both had stopped taking their meds.

The police knew Kerstetter. The police did not know Abdullahi.

The New York Police Department recently adopted a new policy. Any time a known mentally-ill person is the subject of a 911 dispatch, the officers rushing to the scene are notified. In a limited way, DMH did know about Abdullahi. In early December, he had called its helpline and requested services. The other men he was living with in that group house--most of them had been in the system at some point in their lives. Not to mention that the house was operated by Mark Spence; DMH knew him very, very well.

How to respond to the mentally ill has been an issue that the D.C. Police Department has refused to address. For years, they have fielded complaints from residents, from the Office of Police Compliants, and done very close to nothing. I wonder how many more times is the department going to put the lives of its officers at risk? How many more residents in crisis are going to have to die before the department starts to seriously look at its policies? And when is the D.C. Council going to hold hearings on the issue?

I had called Chief Lanier about these issues repeatedly in the wake of Kerstetter's death. I e-mailed her directly twice. I called her office. I called her people. She never called me back. Not once. She never felt it necessary to address the circumstances of Kerstetter's death--she had immediately declared the cops involved as probably justified--nor how her department handles residents in crisis. I have seen Lanier tend to grieving families with a grace and skill few officials can match. I find it difficult to imagine that Lanier hasn't thought about this issue in a serious way.

Earlier today, we wrote about the police shooting that took place this morning at 830 7th Street NE. According to news accounts and police statements, D.C. cops were called to the address for a domestic dispute or assault. When they arrived they found a stabbing victim and the alleged perp. The suspect allegedly charged at the police with a pole. The police opened fire on the man and killed him. “He was dead on arrival. It was a fatal shooting," says Traci Hughes, the D.C. police spokesperson.

The incident happened shortly before 11 a.m. While there was some back and forth over whether the home was a group home, it is a rooming house that does include people who are mentally ill. One former resident I interviewed said that he had been referred to the house by a psych facility. "This is supposed to be a community residential facility," said the former resident of his one-time 7th Street home.

Tonight, the home was empty except for two residents. The former resident was on the scene as well. He talked about the man who had been shot and killed by police. He knew him as "Osmond." Police released his name a few hours ago. His name is Osman A. Abdullahi. He was 36. The former resident said that Osman could be delusional, that he talked often about people out to get him. Some of Osman's enemies were from Alaska. "I would say he was schizophrenic," said the resident. "He talked about people coming to get him."

A month ago, he says, he saw Osman laying on his bed. "He had a butcher knife under [the] covers," he recalled. "He was worried about his roommates. He said the roommates were talking in their sleep about him."

This morning, Osman, attacked one of his roommates, a senior citizen, someone the two current residents referred to only as "Lewis." Grant Osborne, 57, a resident at the 7th Street home, says he woke up this morning to Osman standing in the doorway with a knife. He was fuming about his same old problem: People were out to get him. They were coming for him. Osborne didn't understand. The shades were drawn.

Osborne remembers the police breaking down the door. He heard the police ask Osman multiple times to drop his weapon. He says he heard one shot.
