Daniel Harrison McGrath
McKinley Gail Wilder
ROSEVILLLE, CA - U.S. marshals arrested the grandfather of a toddler who was found dead inside a Roseville home last month on suspicion of possession of child pornography, according to a criminal complaint filed on Friday in the U.S. Attorney's Office, Eastern District of California.
Daniel H. McGrath is being held without bail and federal charges are pending.
Detectives were investigating the suspicious death of McKinley Wilder, who was found dead on April 4, when they found the information.
At the time, McGrath and his wife were out of the country. McGrath's daughter Denise Wilder and her two daughters were staying at the home on the 300 block of Diamond Oaks Road while the couple was out of town.
According to police, when emergency responders arrived at the Diamond Oaks Road home Wilder appeared heavily intoxicated. She was taken to the hospital then arrested on suspicion of murder. Wilder was later released on her own recognizance.
The Placer County district attorney is awaiting results of forensic autopsy tests on Wilder's daughter McKinley to determine if any charges will be filed.
During the investigation, detectives seized more than 100 VHS tapes, five computers, hard drives and CDs from McGrath's Roseville property.
Agents found the information contained thousands of images and videos of child pornography, according to the criminal complaint.
One VHS tape showed two hidden camera videos of victims that appear to have been taken while McGrath and his family lived in the 5500 block of Lea Court in Rocklin at least 18 years ago.
The camera was hidden in a bathroom and bedroom and shows the victims nude. According to the complaint, the victims appeared to be minors at the time the hidden camera video was taken.
The VHS tape also shows several videos that appear to be taken from outside of unsuspecting adult women's windows. The videos captured the women as they undressed, changed their clothes or used the bathroom. A time stamp on one of the videos shows it was taken in August 1991 at 1:56 a.m.
The identity of the women and their location during the video footage is unknown, but detectives believe the architecture of the homes in the videos is consistent with the architecture of the Rocklin neighborhood where McGrath lived.
When a detective told McGrath police would be serving a search warrant at his Roseville home, McGrath said he had "sensitive" information on the computer and associated hard drives, including pictures of his wife and movies from 20 years ago, according to the complaint.
McGrath also told the investigator he had porn on his computer and said, "You are going to go on (the computer) and see some underage stuff ..."
According to the complaint, McKinley Wilder "appeared to have suffered some type of injury to her abdominal area as there was bruising in this area."
McGrath reported Wilder and her children missing after getting a phone call from Wilder's boss, who said Wilder hadn't come to work the past few days, according to the complaint.
