A Chicago woman who said she was having a bad day was arrested for attempted murder for pushing a stranger onto the city’s electrified train tracks on Friday.

Chicago Police arrested Wilma Maxey, 57, for pushing a woman she did not know onto the CTA’s train tracks at a North Rogers Park train station, the Chicago Sun-Times reported.

The suspect told police she was “having a bad day” and “wanted to kill someone” because her bank account had not cleared her to access a sum of cash she was waiting to spend.

Maxey was at the Mores Avenue train stop just before 7:00 a.m. on March 2 when she saw a 66-year-old woman walking down the platform. Police say Maxey then stood up from her bench, walked over to the victim, shoved the woman off the platform and down onto the train tracks. Maxey then allegedly sat back down on the bench, where police found her after being called to the scene by a witness.

One witness tried to help the victim who was knocked unconscious after falling to the tracks, police said. She was taken to St. Francis Hospital in Evanston and was treated for a skull fracture, brain contusions, and an injured jaw.

The suspect was seen sitting calmly on the bench and was arrested without incident.

Maxey was arrested and charged with attempted first-degree murder and ordered held without bail. Maxey claimed she receives Social Security disability checks for a mental illness causing a judge to sign a mental healthcare hold on her.
