An Austin man allegedly threatened two elderly men with a box cutter when robbing them at a South Austin church Tuesday morning.

According to court documents, officers responded to the St. Ignatius Catholic Church near West Oltorf Street and Euclid Avenue shortly before 5 a.m. Dec. 12. Two men, both over 75 years of age, told responding officers that they were volunteers for the church's food pantry.

One victim told police they saw a man, later identified as 52-year-old Mark Anthony Anderson, sitting outside when he arrived at 4:30 a.m., and that he had been helping the two victims unload food for the pantry. The victim told police he invited Anderson inside so he wouldn't be cold, and that once inside Anderson ordered him to lay down on his back and empty his pockets.

According to the affidavit, Anderson robbed the first man before threatening the second man with a box cutter. Anderson allegedly took wallets from both men and the keys to one man's pickup truck, and police say Anderson fled the scene in the pickup.

Police said they identified Anderson through searches of their databases, and both men identified Anderson as the man who robbed them when shown his driver's license.

Anderson has been charged with felony aggravated robbery with a deadly weapon. The affidavit lists his bond is set at $20,000, and he is not listed in the Travis County Jail as of early Friday afternoon.
