According to the report, one of the attackers was renting three apartments in Niigata, including the one across from Maho's room and one near where another of the suspect members lives. Apparently it was being rented out as a "monthly mansion" or short-stay apartment (page 7). Presumably, though I guess it's possible other members had work at the theater besides those performing? Yes. Her statement proper is 2.1.(1).イ, beginning on page 4 and continuing to near the end of page 5. The move to the park is the last line of her statement. What happened after the attack is fleshed out further in 2.1.(1).ォ.(ゥ) on page 8-9 with the accounts of manager(s) and other members.
