Houston police Sgt. Brian Harris confirmed several current and former schoolmates of Moazzam Minhas either knew of the teen's alleged plot before or after Minhas' mother, Tabassum Khan, was fatally stabbed Nov. 25, the Houston Chronicle said Friday.
"Some have come forward and said they knew about the plan after it happened," Harris said. "Some knew about it beforehand, which always amazes me because you kind of wonder about their moral compass."
Nur Mohamed, 18, is accused of stabbing Khan more than 36 times as part of a home invasion. Mohamed and Minhas are both facing capital murder charges and being held without bail.
Harris County prosecutor Connie Spence said Minhas allegedly paid Mohamed for the killing, telling him that Khan treated him badly.
"I'm not sure if the two defendants realize the permanency of what has been done," Spence told the Chronicle.
"I don't know if it's because of their youth or being naive, I'm not sure the gravity of what has happened has fully hit them."
