(AP, ABC7) The younger brother of NFL players Vernon and Vontae Davis has been declared incompetent to stand trial in the slaying of a man visiting the nation's capital from Colorado.

Nineteen-year-old Michael Davis is charged with first-degree murder in the April death of 66-year-old Gary Dederichs. Police say Dederichs was walking alone in a residential neighborhood when he was struck on the head with a hammer or similar weapon.

Davis has also been charged in two nonfatal attacks and is suspected in two additional assaults. All occurred over a 3-day period less than a mile from his home.

D.C. Superior Court Judge Robert Morin declared Davis incompetent to stand trial Friday based on a psychiatrist's recommendation. Davis will be treated at a psychiatric hospital in hopes of restoring his competency.

The suspect was previously arrested in connection with two assault cases and was being held in D.C. Jail at the time of his arrest. He was previously charged with two assaults in April in D.C. Superior Court.

In both cases, he was charged with assault with intent to kill while armed. Davis will have a preliminary hearing in those cases

At the time of his original arrest, police say that Davis may be linked to at least four attacks, including three that took place in a span of 27 hours Tuesday and Wednesday, including the murder of Dederichs.

However, police say in the charging documents that a fifth victim came forward shortly after Davis' arrest. The man alleges that just hours before the young woman was attacked, he was hit in the head by a man at about 3:30 p.m. in the 200 block of Ingraham Street NW.

The victim in that case tells ABC 7 News that he was walking his dog along Ingraham Street that day near an elementary school when he encountered the suspect. He says that he and the man, believed to be Davis, even exchanged pleasantries before the victim was attacked.

It wasn't until the next day, after he sustained multiple head injuries, that he was asked to pick his attacker out of a set of photos. He identified Davis and says he wishes he had reported the attack sooner.

"A young lady was attacked the same day...I felt kind of guilty," he said "If I had phoned it in, maybe she wouldn't have been hurt."

Timeline of the attacks

According to the charging documents, five separate assaults may be connected to Davis.
Date Time Location April 24 6:02 p.m. 800 block of Emerson Street NW April 25 2:42 a.m. 4800 block of Georgia Avenue NW April 25 8:40 p.m. 5600 block of 9th Street NW April 26 3:35 p.m. 200 block of Ingraham Street NW April 26 9:00 p.m. 800 block of Gallatin Street NW

The April 24 incident was the one in which police discovered the body of Dederichs. Davis was arrested after the final assault on Gallatin Street.

Brother of NFL stars

Davis' father confirmed to ABC7's Jennifer Donelan that Michael is the younger brother of San Francisco 49ers tight end Vernon Davis, who starred for the University of Maryland. He says he didn't believe his son Michael had committed the alleged assault. Earlier on Friday, Vernon Davis tweeted about a "disturbing call" he got:

Just got a disturbing call from back home in washington dc. A good day gone bad! Hopefully he wasn't involved!

Another brother, Vontae Davis, is a cornerback for the Miami Dolphins.

Lanier said that Davis was caught on Thursday night after a teenage woman was attacked in the same area as the three other attacks. Police officials have refused to confirm that the suspect is related to the other attacks, but admit that they're similar in nature.

Police say Davis lives on Emerson Street NW, within the 10-block radius where the three attacks occurred. In response to the attacks, police stepped up patrol in the area of Emerson Street and went door-to-door in the neighborhood looking for information.

One of the attacks resulted in the murder of Dederichs, who was visiting the District from Colorado. Chief Lanier previously said that Dederichs and the other two victims, a 53-year-old man and a 37-year-old woman, all suffered head injuries.

Police say that at 9 p.m. on Thursday night, police in the 800 block of Gallatin Street heard screams from a 19-year-old woman and found her lying on the ground with a bad head injury. Soon after, officers located a suspect who began to flee. As he fled, he threw a bag that had a claw hammer inside.

Officers were able to apprehend Davis a short time later in the 4800 block of Illinois Avenue NW. The victim remains hospitalized

The other two attacks both occurred on Wednesday. The first, against the 53-year-old man, happened at about 3 a.m. near the intersection of Georgia and Emerson avenues NW. The second one happened at about 8:40 p.m. in the 5600 block of 9th Street NW.

Kathy Meades says she watched Davis and his two older pro ball players grow up in the home two doors down on Emerson Street.

"I am shocked. I am totally shocked,” she says. “I never would have guessed that in a million years. I am thinking of him as a little boy lovable."

Both of those victims remained hospitalized as of Thursday night as well.

Dederichs was found Tuesday night near the 800 block of Emerson Street NW. Police say Dederichs was a retired registered nurse in his native Denver. He had recently registered to a travel website for people looking for short-term vacation homes.
