Kenneth Alleman Midgley II, 28, was arrested in April after briefly fleeing to Mexico, police say.

Authorities found Midgley's father, 50-year-old Kenneth Alleman Midgley, dead in a freezer on April 15.

The body was found after a welfare check at the home in the 4700 block of Nocona Drive.

The timing of the elder Midgley's death remains unclear because other family members who lived at the house were out of town for two weeks, police said.

The sister of the younger Midgley called police after she hadn't heard from her father for a few days. Her brother had also told their mother that the elder Midgley was dead, according the arrest-warrant affidavit obtained by KDFW-TV (Channel 4).

When officers arrived at the home, they found a note that said, "It's in the freezer," and that something bad had happened. When they looked in the freezer, they found the elder Midgley's body wrapped in a blue tarp.

Officers also found a bloody steel rod and signs of a struggle in the home, the affidavit states.

Midgley was arrested at DFW International Airport after police said he had fled to Mexico. It's unclear where he was before his arrest.

He was booked in the Collin County Jail and held in lieu of $500,000 bail. His first court appearance is scheduled for next month.
