Browsing through newspapers.com, there was an article about an attempted abduction from Glen Burnie Mall the following December. I don't think I can link to it, but here's a summary:
A 20 yr old woman was abducted from the Glen Burnie Mall on Dec. 14, 1970. She had been shopping and came out around 9:15 pm to find her car had a flat tire. A man, about age 30, approached and asked her if she needed help changing the tire. After changing it for her, he convinced her she needed to take the tire to a local tire store for repair. He got into the passenger side seat to ride with her. She pulled out on Ritchie Hwy and when stopped in traffic, he grabbed her by the head and forced himself into the driver's seat. As they drove farther down Ritchie Hwy, they slowed in traffic and she jumped out of the car and began screaming for help. The abductor drove off and she called her father to pick her up. They reported the incident to police who searched and later found her car in flames less than a mile away. The car was destroyed.
The description of the man was similar to that of a man who abducted 2 women and sexually attacked them in a Glen Burnie shopping center parking lot in 1969. He was white, about 30 yrs old, medium length brown hair and about 5 ft 10 in tall, with a medium build.
From The Capital, 16 Dec 1970
That's 4 women attacked, one killed in 1969-70 all abducted from the same area.
It sounds as though there was a serial rapist/abductor in the area who escalated to murder. He either lived in the area and walked home after his crimes or stashed a car nearby.
