DNA on napkin cracks 32-year-old case
Washington, June 23 : DNA evidence from a discarded restaurant napkin was used to identify a suspect in the slaying of a 12-year-old girl in 1986 in Seattle, Washington, police said.
Gary Hartman, 66, was arrested on Wednesday and has been charged with murder in the first degree and rape in the first degree, Tacoma Police Chief Don Ramsdell said at a news conference on Friday about the cold case.
Hartman will be arraigned on Monday, CNN reported.
According to police records, Michella Welch and her two younger sisters went to the city's Puget Park on March 26, 1986.
About 11 a.m. Michella rode a bicycle home to get lunch. While she was gone, the sisters went to a business to use the restroom, Ramsdell said.
"A search dog found Michella's body that night in an isolated area, more than a quarter mile away from the play area," Ransdell said. She was sexually assaulted and murdered. In August 1986, another girl Jennifer Bastian, 13, was killed.
Two brothers were identified as possible suspects and surveillance began leading to a detective follow Hartman into a restaurant when he met a co-worker for coffee, CNN quoted Ramsdell as saying.
"I observed him using the napkin multiple times," the detective said.
"He crumpled it up, put it into a bag and then crumpled that bag up and voluntarily abandoned that bag as he left the restaurant."
The napkin was collected and sent to the Washington State Patrol Crime Laboratory. On Tuesday, the lab told police the DNA on the napkin matched DNA found at the crime scene.

ISRO launches Mission MITRA for safety of human spaceflight mission crew
Bengaluru (PTI): ISRO on Friday said it has undertaken mission MITRA in Leh, Union Territory of Ladakh, from April 2 to 9, a first-of-its-kind team behavioural study for the benefit of human spaceflight missions such as Gaganyaan.
The mission, inaugurated by the ISRO chairman V Narayanan, was mainly for the crew safety and performance.
"Mission MITRA is a first-of-its-kind team behavioural study designed by ISRO and IAF-Institute of Aerospace Medicine to examine the physiological, psychological, and operational dynamics of Crew and ground teams functioning in a high-altitude environment," ISRO said in a statement.
This study is targeted to generate vital understanding on the team interoperability between crew (Gaganyatris) and ground control teams and the effectiveness of decision making under environmental & operational stress, the space agency said.
Noting that the crew safety and performance are the most critical elements of all Human Spaceflight Missions, ISRO said the ability of the crew to communicate effectively, adapt to stress, maintain psychological resilience and support one another determines the success and safety of any mission.
Analogue missions conducted under controlled yet realistic conditions are utilised to understand how crews perform under challenging conditions, it added.
The space agency said the high altitude of approximately 3,500 meters at Leh having the environmental conditions of hypoxia, low temperature, and isolation, is a natural analogue for spaceflight operations.
