The suspect in a series of hammer attacks in the Petworth neighborhood of D.C. passed a drug test given at the time of his arrest, according to a Washington Post report.
A D.C. Superior Court judge ruled last week that 19-year-old Michael Davis was incompetent to stand trial for his alleged crimes. Davis, the younger brother of NFL players Vernon and Vontae, had been charged with first-degree murder in one of the assaults, which resulted in the death of 66-year-old Gary Dederichs, a tourist from Denver. Davis was also charged with two counts of assault related to two other attacks.
According to a report, which was released Thursday by D.C. Superior Court Judge Robert E. Morin, the drug test was prompted by an unidentified witness who told police that Davis had a "history" of using PCP.
A staffer at St. Elizabeth's Hospital spent about four hours with Davis after his arrest on April 28, and reported that the suspect "exhibited little energy or excitement" during the interview and gave short answers to questions.
Another hearing for Davis is scheduled for July 13, following further examinations at St. Elizabeth's
