It was not until 1:30 a.m. that night that a female jogger was found in the North Woods area of the park. She had been pulled to the north some 300 feet off the path known as the 102nd Street Crossing; the path of her feet dragged through the grass was marked so clearly that it could be photographed. It was 18" wide. There was no evidence in the grass of footprints of multiple perpetrators. She was brutally beaten, suffering major blood loss and skull fractures; she was later revealed to have been raped.
Trisha Meili was going for a regular run in Central Park shortly before 9 p.m. While jogging in the park, she was knocked down, dragged nearly 300 feet (91 m) off the roadway, and violently assaulted. She was raped and beaten almost to death. About four hours later at 1:30 am, she was found naked, gagged, and tied, and covered in mud and blood, in a shallow ravine in a wooded area of the park about 300 feet north of the path called the 102nd Street Crossing. The first policeman who saw her said: "She was beaten as badly as anybody I've ever seen beaten. She looked like she was tortured."
David Lewis, the banker, attacked and robbed about 9:25–9:40 Robert Garner, attacked about 9:30 p.m. David Good, attacked about 9:47 p.m. John Loughlin, the 40-year-old teacher, severely beaten and kicked about 9:40–9:50 p.m. near the reservoir and left unconscious. He was also robbed of a Walkman and other items.
At 9 p.m. on April 19, 1989, a group of an estimated 30 – 32 teenagers who lived in East Harlem entered Manhattan's Central Park at an entrance in Harlem, near Central Park North. Some of the group committed several attacks, assaults, and robberies against persons walking, biking, or jogging in the northernmost part of the park and near the reservoir, and victims began to report the incidents to police. Within the North Woods, between 105th and 102nd streets, they were reported as attacking several bicyclists, hurling rocks at a cab, and attacking a pedestrian, whom they robbed of his food and beer, and left unconscious. The teenagers roamed south along the park's East Drive and the 97th Street transverse, between 9 and 10 p.m.
Michael Vigna, a competitive bike rider hassled about 9:05 p.m. by the group, one of whom tried to punch him. Antonio Diaz, a 52-year-old man walking in the park near 105th Street, was knocked to the ground by teenagers about 9:15 p.m., who stole his bag of food and bottle of beer. He was left unconscious but soon found by a policeman. Gerald Malone and Patricia Dean, riding on a tandem bike, were attacked on East Drive south of 102nd Street about 9:15 p.m. by boys who tried to stop them and grab Dean; the couple called police after reaching a call box.
The police were dispatched at 9:30 pm and responded with scooters and unmarked cars. Through the night, they apprehended about 20 teenagers. They took custody of Raymond Santana, 14; and Kevin Richardson, 14; along with three other teenagers at approximately 10:15 pm on Central Park West and 102nd Street. Steven Lopez, 14, was arrested with this group within an hour of the several attacks that were first reported to the police. He was also interrogated.
At least some of the group traveled further south to the area around the reservoir, where four men jogging were attacked by several youths. Among the victims was John Loughlin, a 40-year-old schoolteacher, who was severely beaten and robbed between 9:40 and 9:50. He was hit in the head with a pipe and stick, knocking him briefly unconscious. At a pre-trial hearing in October 1989, a police officer testified that when Loughlin was found, he was bleeding so badly that he "looked like he was dunked in a bucket of blood".
