Court documents: Widefield man raped, beat grandson

A Widefield man raped his 8-month-old grandson before beating him so severely that the boy died of his injuries, El Paso County sheriff's investigators alleged in court documents.

Willie B. Allmon, a 51-year-old registered sex offender, was arrested Thursday on suspicion of first-degree murder in the death of Isiah Wilson.

Allmon is being held without bail in the El Paso County jail. His first court appearance is Wednesday.

El Paso County sheriff's deputies went to Allmon's home at 46 N. Albion St. on Monday after a caller summoned an ambulance to check on an unresponsive infant having difficulty breathing.

Doctors at Memorial Hospital determined the child had suffered severe head injuries - apparently the result of abuse - and had been raped, investigators said in an arrest affidavit obtained Friday.

The child was placed on life support and died Tuesday. An autopsy determined the cause of his death was a blow to the head in what the coroner's office called a homicide, the fourth in unincorporated El Paso County this year.

In 1998, Allmon was arrested on suspicion of aggravated incest and sexual assault. He pleaded guilty to a misdemeanor sex offense. No other details were available, but according to the sex offender registry, he fondled a child.

The same year, Allmon's then-wife Monique Allmon petitioned the courts for protection from him, claiming that he choked and threatened her and held her against her will.  She said their final break came in April of 1998 when he warned her he had a gun close by and would use it on anyone who got in his way.

She wrote in court documents that he told her, "As long as my name is Allmon, I belong to him."

A female relative was granted a permanent restraining order against Allmon in 2002 after accusing him of sexually abusing her.
While being questioned about Isiah's injuries, Allmon gave deputies two different accounts, an arrest affidavit shows.

He initially claimed he left Isiah on his bed when he went to use the bathroom. He heard a thud. On the floor was Isiah, with a dirty diaper. Allmon claimed he passed out as he knelt down to change the diaper.

He claimed he awoke on top of the infant. Isiah was gurgling, and his eyes rolled back in his head.

Later, Allmon changed his story.

He told deputies he accidentally banged Isiah's head on the kitchen counter and dropped the child while attempting CPR. He denied raping his grandchild.

Allmon initially was arrested Tuesday on suspicion of felony child abuse and was released after posting a $25,000 bond.

Allmon was arrested again Thursday night after the child died and an arrest warrant accusing him of first-degree murder was issued.
