While authorities say they believe the grenade is dead, they are taking extra precautions to ensure the safety of the home's residents and surrounding neighbors. Police have evacuated families in homes directly adjacent to the one housing the grenade.
The resident who owns the grenade had called authorities to remove it because he didn't want it anymore, Lt. Bob Anderson said. Scanner reports indicated that as of 1:03 p.m., police had already entered the home to collect the grenade.
