GRAND JUNCTION, Colo. -- Blood tests are expected early this week in the case of a missing mother and daughter from Grand Junction.

Some neighbors of the man whose wife and daughter turned up missing almost three weeks ago found the family friendly. Others found them reclusive.

Michael Blagg's Appeal Talks About The Disappearance.

Michael Blagg, has not been identified as a suspect in the disappearance of Jennifer Blagg and her 6-year-old daughter, Abby (pictured, left), but he has not been ruled out either, investigators said.

"I absolutely had nothing to do with their disappearance," Blagg said after finally being allowed to return to the family home that had been considered a crime scene for 17 days. "If I knew where they were, I would have brought them home.

"I am a follower of Christ, and I want to also say that Jennifer and Abby are Christians. If they don't come home to me, they are home in Heaven, but my selfish hope is that they will come home to me."

Blagg reported the disappearances on the afternoon of Nov. 13 after arriving home to find the back door open and a pool of blood in the master bedroom, he said.

The Colorado Bureau of Investigation was expected to send the results of tests on that blood to investigators early this week. It's hoped the tests will tell them whose blood was in the master bedroom.

Blagg had left home around 6 a.m. for work on Nov. 13. That's the last time he said he saw his family.

Four times, Blagg said he received no answer to his usual telephone calls to make sure his family was awake, and to check on dinner plans.

"There have been times we couldn't get ahold of each other," he said. "I never called the school because I didn't want to disrupt the class."

Abby and her mother had never arrived at Abby's school, but no one at the school called the home to find out why.

Investigators have several theories about the disappearance: one or the other of the parents is responsible, an unsuspected enemy is responsible, an intruder mistook the Blagg home for the home of next-door neighbor Tammy Eret, a Mesa County deputy district attorney.

"I've been threatened," said Eret, 33. "For my own safety and reassurance, I wanted to know if the focus on the investigation was on a stranger or a family member, and I felt quite reassured they aren't looking for a stranger." A neighbor, interviewed by investigators, said that she thought it was curious that Michael Blagg drove up and parked in front of the house the afternoon of the disappearance, instead of in the empty driveway.

The family had first rented a home north of downtown on a block populated by older couples.

"They were just a beautiful young family," said neighbor Char Shoffner. "It was just a delight to have them in the neighborhood."

In January 2001, they moved to a larger home west of downtown.

"I don't think anyone on the block knew them," Eret said.

Jennifer Blagg, 34, blond with brown eyes, grew up in small towns in Oklahoma. She often could be found at regular church youth group meetings.

After her parents divorced, Jennifer moved to San Diego. She met Michael Blagg at a party.

Blagg, 38, grew up an officer's son on Air Force bases from Georgia to Hawaii. The man with the direct greenish-brown eyes and a confident handshake delivered pizzas to attend Georgia Tech to become an engineer. He enrolled in Navy ROTC and entered pilot training after graduation in 1985.

The couple wed Nov. 16, 1991, in Fort Worth, Texas.

Michael Blagg left the Navy in 1995 as a lieutenant commander, joining a company in the Phoenix area.

After moving to South Carolina, the Blaggs helped form the Intercessory Prayer Ministry, which they also tried to start in Grand Junction. The program has as its goal prayers said 24 hours every day from around the world.

Nearly three weeks after Jennifer and Abby Blagg were reported missing, investigators are frustrated by the lack of progress in the case.

"Nature abhors a vacuum, and investigators abhor a mystery," Sheriff Riecke Claussen.
