News: Study of Internet Crimes
Against People and Children
Mid-Missouri task force sees great potential for growth.
By JOE MEYER of the Tribune’s staff
Published Sunday, January 18, 2009
As the Mid-Missouri Internet Crimes Task Force enters its third year, investigators said there is plenty of
work to do as online predators come up with new ways of preying on children.
"It’s just going to get crazy," task force Detective Tracy Perkins said. "Technology is going to eat us alive,
but we’ll just have to combat it however we can."
One of 10 Internet task forces in the state, the Mid-Missouri group serves seven Mid-Missouri counties
and has partnerships with 20 area law enforcement agencies, Detective Andy Anderson said.
It started in January 2007 investigating online crimes against children and now employs three Boone
County sheriff’s detectives as well as a University of Missouri police captain who works part time with
the task force. A Columbia police detective is expected to rejoin the unit this year after completing a tour
of duty in Kosovo.
In their offices south of Columbia, at 5551 S. Highway 63, task force detectives keep on each desk several
computer monitors to use in conducting undercover online investigations. They also use the computers
in their examinations of computer hardware seized with court-ordered search warrants.
Anderson has led the local effort in pursuing online predators, working Internet crimes since 1999. He
has been investigating crimes against children for more than 20 years with the sheriff’s department.
Anderson hopes additional state grant funding can lead to expansion of the task force.
Cases investigated by the task force have a broad reach, resulting in suspects arrested across Missouri as
well as other states on state and federal charges. And earlier this month, felony charges were filed
against a Missouri man serving as an Army reservist in Iraq. He is accused of exposing himself over the
Web to a task force investigator posing online as a teenage girl.

News: Herhold: Digital Clues Add Insight
to Achilli Slaying in Los Gatos
By Scott Herhold
Posted: 01/05/2009 07:31:17 PM PST
In the old days, detectives used physical clues to solve crimes: Colonel Mustard killed Miss Scarlet in
the living room with a candlestick because nothing else made sense.
In our brave new electronic world, we employ Google searches, BIOS clocks and text messages. And
nothing illustrates the tracks left in the digital snow better than the Mark Achilli murder case.
The prosecution wrapped up its testimony Monday in the preliminary hearing for three men accused of
Achilli's murder: Esequiel "Paul" Garcia, 30, the bar and restaurant owner alleged to have paid for the
killing; Miguel Chaidez, 22, a Southern Californian who allegedly arranged logistics; and Lucio Estrada,
25, the suspected triggerman.
Online evidence
The prosecution's witnesses centered on one powerful piece of digital evidence — a Metroactive.com
picture of the victim, Achilli, outside the 180 Restaurant & Lounge before he sold the club and
Mountain Charley's saloon to Garcia in September 2007.
Police say the gunman used a copy of that picture to identify his mark in the March 14 murder at 18400
Overlook Road in Los Gatos. The image was left torn in two in bushes not far from the scene.
What was new Monday were the details of who had sought to view the same online picture of the
somewhat bedraggled entrepreneur standing next to the logo for his club.
