The mother of two children found hanged in their Berks County home was being arraigned Monday morning on first-degree murder in the children’s death.

Lisa Snyder was arrested a short time before 9:30 a.m. at her home, and was being arraigned on murder, child endangerment, and related charges before a district judge, Pennsylvania State Police Trooper David Beohm said in a news release.

Murder is a non-bailable offense, and Snyder will be sent to Berks County Prison.

A news conference is scheduled for 2 p.m. with District Attorney John Adams at the Berks County Courthouse. Dennis Charles is listed as Snyder’s attorney; he was not in the office and could not be reached for comment.

Siblings Conner and Brinley Snyder, ages 8 and 4, were found unresponsive Sept. 23 hanging from opposite ends of a plastic-coated dog lead that was looped over a rafter in the basement of the home in the 2400 block of Route 143 in Albany Township, outside Kempton.

The pair were revived and flown to Lehigh Valley Hospital in Salisbury Township, but three days later were taken off life support and pronounced dead 14 minutes apart.

Lisa Snyder, who turns 37 on Dec. 13, told a 911 operator her son had been bullied and “didn’t want to go alone.”

The results of the children’s autopsies were inconclusive and their deaths have been under investigation by authorities.

On Monday, Lehigh County Coroner Eric Minnich said he ruled the cause of death for both children to be hanging, and the manner for both to be homicide, following an "extensive investigation and collaboration with the Pennsylvania State Police – Hamburg Barracks and the Berks County District Attorney’s Office."

Investigators filed a series of search warrants for items in the home, including cell phones, and a black husky-pit bull mix as part of the investigation, according to The Morning Call.

Lisa Snyder is being charged with two counts each of first-degree murder, third-degree murder and child endangerment, as well as single counts of sexual intercourse with an animal, tampering with evidence and animal cruelty.
