According to his biography he was involved in many crimes:
As a teenager, Wahlberg participated in several acts of violence and vandalism. He later claimed to have been in trouble 20-25 times with the Boston Police Department as a youth. By the age of thirteen Wahlberg had developed a serious addiction to cocaine and other substances. At fifteen he harassed a group of African American school children on a field trip by throwing rocks (causing injuries) and shouting epithets. When he was sixteen (again using racist language) after robbing a pharmacy under the influence of PCP, Wahlberg knocked a middle aged Vietnamese man unconscious, left another Vietnamese man permanently blinded in one eye, and attacked a security guard.  For these crimes, Wahlberg was charged for attempted murder, pled guilty to assault, and was sentenced to two years in jail at Boston’s Deer Island House of Correction, of which he served 45 days. In yet another incident, the 21-year-old Wahlberg fractured the jaw of a neighbor in an unprovoked attack.
