Kernrechtsfrage
Whether the appellate court had to order a psychiatric expert opinion under Art. 20 StGB for sentencing and possible measures.
Extrahierter Entscheid
No serious grounds existed to doubt full criminal responsibility; the refusal to order an expert opinion did not violate Art. 20 StGB.
Extrahierte Begründung
The defendant's youth, unusual statements, alleged submissiveness to a co-offender, and family hardship did not establish concrete indications of impaired capacity. His behavior before, during, and after the offenses showed intact reality testing and adaptability; moreover, later treatment in 2005 could not explain responsibility for earlier offenses.
