Just in case there is anyone reading here who can't access the articles that describe the crimes, here is a summary:
1. Early morning hours of August 18, 2007: a 23 year old woman was looking for her car in the area of State Street in downtown Boston. She was approached by a male thought to be in his twenties with light olive skin and brown hair whom she thought she knew. She accepted a ride from him to help look for her car but instead he took her to Terminal Street in Charlestown. He threatened to kill her and said he had a weapon and she was assaulted near the railroad tracks.
2. November 22nd, 2007: another 23 year old woman left a bar on State Street and entered a vehicle that she believed to be a taxi or other livery car. She gave the male driver the address of an ATM near her apartment. He showed this victim a knife and drove to Terminal Street where she was ordered out of the car and assaulted.
3. August 5, 2008: A 36 year old woman was panhandling in the area of Boylston and Arlington Streets, off the Boston Common/Public Garden. She was approached by a man in his early twenties, who promised to give her money if she went to Charlestown in his car with him. The man drove her to Terminal Street, tackled her to the ground, held a gun to her back, and assaulted her repeatedly.
4. December 23, 2008: a 44 year old woman was jogging in the area of Terminal Street when a man ran up behind her and tackled her to the ground. During this assault, in which he claimed to have a gun, the victim was able to use her gloved hands to poke at his eyes. When the attacker ran off, the victim was able to return home and call 911.
In the first three incidents, the victims were able to flag down passersby for help and be taken to hospitals to have forensic exams performed. In each case, a male DNA profile was established from assault kit swabs that matched a single unknown attacker. In the fourth incident, the victim's clothing (including her glove) were taken into evidence but no forensic link to the previous three cases was established at that time.
