HOUSTON (AP) _ Police in Houston say a murder suspect who lost weight so he could escape from jail by squeezing through a vent has been caught taking a dip in a motel swimming pool.

Police say Darryl Layne Norris was back in custody Wednesday. Authorities say Norris escaped early Saturday from the Waller County Jail in Hempstead, about 50 miles northwest of Houston.

Investigators said he escaped through an air conditioner vent that is less than one foot wide. Waller County Sheriff Randy Smith said Norris usually weighs about 160 pounds but had been losing weight. Norris is charged with murder in connection with a convenience store robbery.
