Boston Police commissioner Ed Davis told Fox News Sunday that the Boston Marathon suspects may have been planning more future attacks.
Davis said that the amount of explosives police found at the scene suggested that the suspects "were going to attack other individuals."
Davis told CBS' Face The Nation that over 250 rounds of ammunition, several explosive devices and homemade grenades were among the weapons found.
19-year-old Dzhokhar Tsarnaev is currently hospitalized due to serious wounds. His condition is serious, but stable. Doctors say he is not yet able to talk. His older brother Tamerlan Tsarnaev was killed during a shootout with police on Thursday night.
"This was as dangerous as it gets in urban policing," Davis said of the firefight.
The two brothers are accused of planting the bombs that killed 3 and injured around 180 others at Monday's Boston Marathon.
Davis also told Fox News that the FBI not yet been able to question Tsarnaev due to his condition, but he's "progressing."
Dianne Feinstein also appeared on Fox News Sunday, telling host Chris Wallace that there is evidence from the bombings that implicates the younger Tsarnaev.
