EL PASO, Texas (AP) _ The investigation into the death of former Texas-El Paso basketball star Hernell ''Jeep'' Jackson has resulted in the arrest of a second woman on cocaine charges.

Thelma Apodaca, 24, was charged Monday with delivery of less than an ounce of cocaine. She was held in El Paso County Jail under $100,000 bond.

Five days earlier, police arrested Michelle Cabrera, 19, on charges of delivering less than an ounce of cocaine to Jackson the night before he died while playing a charity benefit basketball game at Fort Bliss on May 2.

Apodaca's lawyer, Gary Hill, said police allege she supplied Cabrera with the cocaine that later went to Jackson. Cabrera is free on $500,000 bond.

Jackson, a 23-year-old All-Western Athletic Conference player, died about five minutes into the game.

An affidavit last week by Detective Joe Garcia said police ''believed that cocaine was the contributing factor to the death.''

Autopsy results were inconclusive about the cause of death, and the county medical examiner said he was awaiting the results of tests on blood, tissue and urine specimens.

Hill said police arrested Apodaca after she voluntarily went to talk to them.

''We knew they had been looking for her, so we called them,'' Hill said. ''When she refused to comment, they arrested her.''

According to the arrest affidavit, Cabrera and Jackson went to his apartment the night of May 1 and ingested cocaine.

A search warrant and Garcia's affidavit said other people were at the apartment, but police have not identified them.
