A city man is behind bars on involuntary manslaughter and related charges in the death of his infant son in 2022.

Robert Paul Charles Jenkins Jr., 34, was arrested Monday after a nearly three-year investigation into the death of the 8-week-old child.

According to Altoona police, the death of the baby on Sept. 5, 2022, was originally attributed to SIDS (Sudden Infant Death Syndrome). However, several months later, upon return of the toxicology reports, it was found that the infant had a BAC of 0.149 along with methamphetamine in his system.

The death was then attributed to alcohol intoxication.

Following a lengthy investigation that included several witness statements, it was determined that Jenkins was the sole adult present at the residence at the time of the incident and the only individual that could have administered the fatal dose of alcohol.

Jenkins was arraigned Monday before Magisterial District Judge Benjamin Jones on a charge of involuntary manslaughter, three felony charges of aggravated assault, a felony charge of endangering the welfare of children and misdemeanor charges of recklessly endangering another person and possession of drug paraphernalia.

Unable to post $100,000 bail, he was remanded to the Blair County Prison.

His preliminary hearing is set for Aug. 27 before Jones.
