Stilwell with Criminal defense attorney Callahan

Robert J Callahan wins Stilwell Murder Trial

Cody Stilwell, the 21-year-old man accused of stabbing his ex-girlfriend’s stepfather in 2014, was acquitted on Friday almost 25 months to the day after he was first arrested. The jury took less than three hours to come back with the not guilty verdict. Stilwell was shackled and led out of the courtroom, showing little emotion as if in disbelief that he was going to spend the Memorial Day weekend at home with his family. A family member of David Kennett II, whom Stilwell stabbed — he said it was in self-defense — began sobbing and needed help out of the courtroom. Tears were also shed on Stillwell’s behalf.

  • I had a fairly serious legal issue but was fortunate to be put in touch with Mr. Callahan. He is highly skilled, extremely competent and very attentive. I am what you would consider a high maintenance client who needed to be intimately involved in my case. Mr. Callahan always returned my calls, was proactive and committed to helping in win my case. He exudes extreme confidence and was always willing to go the extra mile. He even visited me in jail late at night, how many other attorneys would do that. Never underestimate the power of a good attorney. The state knows who the good attorneys are and they are far less likely to pursue a marginal case if they know who they are up against. For me, my felony case was dropped, I considered it a miracle. Don’t risk your future, go with the best you will be happy you did.

The FBI has Questioned me; do I need an attorney?

If the Federal Bureau of Investigations has already questioned you, you may. The answer to this question lay in whether the FBI has reason to suspect you in the commission of a crime.

There could be a few reasons the FBI wanted to ask you some questions. These include:

  • General information

    If you happened to be near to where a crime was committed, you may have some general, linking information which will help in their investigation. You may have nothing to do with the crime and are not even considered a suspect. But investigators often question everyone who may know anything.

  • Specific Information

    Investigators may have uncovered your name in connection with a crime. They may not suspect you of anything, but may believe you have information useful to their investigation. You may be aware of this knowledge or not.

  • You Are a Suspect

    Legally, investigators have an obligation to inform you that you are a suspect. However, this does not always happen, as attested by the numerous Supreme Court challenges along these lines.
