Terry Thompson pleaded guilty to second-degree murder while armed through his attorney, Kevin O’Sullivan, before DC Superior Court Judge Rainey Brandt on April 4.
Thompson, 33, is charged with first-degree premeditated murder while armed, possession of a firearm during a crime of violence, and unlawful possession of a firearm with a prior conviction of less than one year for his involvement in the fatal shooting of Christopher Callahan, 64, on May 15, 2023. The incident occurred outside a 7-Eleven on the 3900 block of Martin Luther King Jr. Avenue, SW.
Thompson previously rejected two plea offers brought by the prosecution. In the plea agreement Thompson accepted, the prosecution agreed to dismiss all other charges besides the homicide in exchange for his guilty plea. Thompson must also register as a gun offender.
According to the prosecution, surveillance video footage shows Thompson walking up to Callahan, who is sitting on his walker, and shooting him in the head outside a 7-Eleven in broad daylight. The incident, prosecution said, happened after a verbal altercation between Thompson and Callahan.
Thompson’s sentencing is scheduled for June 6.
