Charges have been upgraded against the manager of a Northwest Side bar who is accused of killing a man with a punch to the side of the head late Sunday night.

Daniel Longoria, 36, was initially charged with aggravated assault causing serious bodily injury but now faces a charge of manslaughter.

According to the police report on the incident, Longoria asked 30-year-old Mitchell Sanderson to leave the Lost Bar & Grill at 12730 NW Military Highway around 11:15 PM Sunday after throwing a beer bottle.

Sanderson walked outside the bar just beyond the patio and stood between two cars in the parking lot.

Longoria told police he followed Sanderson and asked him to leave again and Sanderson made “derogatory comments” toward Longoria.

Sanderson tried to throw a punch but Longoria was able to block the blow, he told police, and he then punched Sanderson once in the temple.

Sanderson collapsed and was taken to University Hospital in critical condition. He later died.

According to the report, investigators reviewed surveillance video which revealed that Sanderson never tried to throw a punch, only Longoria did.

Employees of neighboring businesses say the bar & grill changed ownership six months ago and has not had any similar incidents.
